Will and Kate are making a trip to California, and we're time warping back to when William's mother, Princess Diana, first visited the United States in 1985 and met then-President Ronald Reagan and Nancy Reagan at the White House.

A single Diana was back in Manhattan in 1995 for the CFDA Gala, and a fan begged her to move to New York!

From L.A. to the streets of New York, celebs are out and about in this edition of GPS!

In L.A., proud new dad Nick Cannon provides an update on his and Mariah Carey's new twins, Monroe and Morrocan. Meanwhile, Corey Feldman shares his opinion about the death of Osama bin Laden.

The last few years have been a whirlwind for "Glee" star, Lea Michele. Almost immediately after the show debuted in 2009, the always-stylish Lea demonstrated her fashion forward sensibilities with every snap of the photographer's camera.

Let's rewind the clock on Lea, and check out a few of her best and worst red carpet moments!

Only a few more days until Junior prom hits McKinley high on 'Glee,' and lucky us! -- we caught up with some of the cast as they dished a spoiler or two about the episode everyone's been waiting for.

Although Jane Lynch remained infuriatingly tight-lipped about the specifics, she promises "there will be a great shocker who wins" the prom king and queen titles. What she can tell is that "everyone" performs a number, including Blaine (Darren Criss), featuring "amazing" numbers by New Directions.

Undoubtedly, one of the most anticipated of events is an intense scene in the upcoming episode's teaser, which features an angry Quinn (Dianna Agron) slapping Rachel (Lea Michele) at some point on Prom Night. When asked about the confrontation, Lea Michele said the slap was inevitable between the characters, but the upside of it is "pretending to be slapped is hilarious."

Darren Criss admits he didn't attend his senior prom because he was grounded, but was able to tag along at a friend's. He says, "if anything [the fake prom] was a little more fun" because I was making a living out of it as opposed to stressing out about it."

On May 5, 2004 the cast of "Frasier" gathered together again to celebrate the end of their iconic sitcom at the cast and crew wrap party.

Stars Kelsey Grammer, David Hyde Pierce, Peri Gilpin, and Jane Leeves walked the red carpet to talk about their show coming to a close. When they entered the party venue, they were greeted by a wall full of episode scripts, a shelf full of Emmys won by the show, and screens playing classic clips from the sitcom's eleven season run.

The show began as a spin-off of "Cheers" with Grammer's character Dr. Frasier Crane moving from Boston to Seattle where he hosted a psychology themed talk radio show.

For her first of two songs on Wednesday's "American Idol," Haley Reinhart gave fans a special first listen to an unreleased Lady Gaga song. Did the judges find it gagalicious or did it just make them gag?

With Lady Gaga's blessing, Haley sang "You and I." The reviews of her performance were less than favorable from Jennifer Lopez and Randy Jackson. Mentor Jimmy Iovine suggested she take a stab at the brand-new song, but JLo said, "I'm just not sure that was the best advice." Randy reviewed, "I'm not so sure it's that great of a song… It's so risky to come out and do something no one's familiar with."

But, Haley had Steven Tyler in her corner. "When someone can take a song they don't know and make it work, that's a beautiful thing," he said. "I think you're just one perfect song away from being American Idol." Watch the video to draw your own conclusion of Haley's voice.

Earlier this week, Lady Gaga revealed the track listing of "Born this Way." The upcoming album, which releases on May 23, does feature "You and I."

Will Haley get the chance to redeem herself in the eyes of JLo and Randy next week? Find out on the "American Idol" results show, Thursday on Fox.

With Prince William and Kate Middleton readying for their royal honeymoon, we're time warping back to when Prince Charles and Princess Diana embarked on their own honeymoon.

Back in 1981, Charles and Diana went on an 11-day honeymoon cruise around the Mediterranean on the royal yacht named Britannia – a perfect way to evade the paparazzi. Later, they headed to the family's Balmoral estate in Scotland and faced the press, with Charles wearing a traditional kilt, and fielded a few questions about newlywed life.

George Clooney's girlfriend Elisabetta Canalis took it all off during a photo shoot for a new PETA campaign and we've got an exclusive behind-the-scenes look!

Elisabetta tells TheInsider.com she knew that getting naked for People for the Ethical Treatment of Animals would attract a lot of attention but said this was a big reason to do it -- to draw attention to the plight of animals killed for fur or consumer products. "I think this is the best reason why I got naked in my life," she said.

The Italian model and actress said her strong opinions on protecting animals were formed when she was very young. "I was a kid, a little girl, and was watching TV at home and they showed a documentary. And in the documentary, I saw how they killed little animals, like electrocuting them, drowning them, bludgeoning them. I was shocked because I was a little girl, but by that moment I thought that I would never, never, never, wear fur in my life."

Watch the video to see Elisabetta's sexy photo shoot and watch for the new PETA campaign this fall.

Elisabetta has appeared in other high-profile campaigns in the past, including one last year for Roberto Cavalli underwear.

Newlywed John Krasinski stopped by "The Ellen DeGeneres Show" to promote his new film 'Something Borrowed,' and ended up letting loose about how quickly he fell in love, and ultimately proposed to his wife, actress Emily Blunt.

John admits to Ellen that the romance caught him by surprise, saying "It's one of those things where as soon as you meet someone you kind of know," explaining that he "wasn't really looking for a relationship and I was thinking I'm going to take my time in LA and everything. Then I met her and I was so nervous. I was like, oh god I think I'm going to fall in love with her. As I shook her hand I went, 'I like you.'"

When it came time to propose, John says he had to do it "real fast" before she could realize she could "have anybody" she wanted, adding that his method of proposing was to slip the ring on her finger without explanation. Of course, she said "yes."

Watch the video for a preview of John's interview with Ellen set to air Wednesday, May 4th on NBC.

Back on May 4, 1998, singer Isaac Hayes was busy recording the voiceover tracks for his character Chef on the hit animated show "South Park."

Hayes' character Chef would become an iconic character on the show who was known for being the voice of reason in town, but also the one who would consistently go off on a sexual tangent in his conversations.

Hayes would be a part of the cast from 1997 until 2005 and even earned a nomination for a NAACP Image Award for Outstanding Lead Actor in a Comedy Series.

Watch the video above to see one of Hayes' early voiceover recording sessions.

Amid the fashion frenzy at The Met Costume Gala in New York City Monday night, possible presidential hopeful Donald Trump actually had something positive to say about Barack Obama's performance.

"I was very proud of the country; it was just a great thing that happened, and they did really a great job," Trump told our own Lara Spencer in reference to the killing of Osama bin Laden. "I think it's absolutely great that they got him and you can't treat him too harsh. I'm really happy about it. … He truly deserved it, and worse."

Asked if he's done with the "birther" third-degree questioning now that Obama has finally produced a long-form copy of his birth certificate, Trump beamed, "Well I hope so, I think it's great. … Well, I do take credit, but I'm focused on other things like the economy."

Shifting the conversation to wife Melania, Trump praised, "She's beautiful. She looks great and it's a great evening."

Stars showed up to Monday night's MET Costume Institute Gala in New York donning their most stunning and daring ensembles, but it was Beyonce who got the most attention -- and not for her eye-catching Pucci gown.

On this day seven years ago, 'Van Helsing' made its premiere in Hollywood, CA.

Starring Hugh Jackman and Kate Beckinsale, the film paid homage to Universal Studios' horror monster films from the '30s and '40s as well as got its inspiration from Bram Stoker's popular Dracula novel.

Coming off his portrayal of Wolverine in the X-Men films and his foray into Broadway with Carousel, Hugh took on the title character in the film that grossed over $300 million worldwide. He even claims that he prepared for his role in the play The Boy from Oz while filming the horror/action flick.

Check out from the 'Van Helsing' premiere and what Hugh's favorite horror film was in the video!

Our "Insider" correspondent Christina McLarty caught up with Hines Ward and Partner Kym Johnson in a moment of triumph after scoring their first "10." The "Dancing" couple started off crediting the night's high scores to their very close relationship, but ended up sharing just a little too much information. 

It's a bit of an understatement when Kym says she and Hines "know each other pretty well." Hines says they've become so close, he "popped a pimple on [Kym's] nose" during practice. As if that wasn't enough, he adds that he has also "passed gas in [Kym's] face." Wonderful.

Mark Ballas also had a bit of an awkward moment during Monday's show when contestant Romeo got a little too up close and personal with Mark's mother Shirley Ballas. She popped by the show for a lesson, but ended up doing a bit of a "freak dance" with Romeo.

Watch the video to check out what Mark had to say about his mother dancing with Romeo, and don't miss an all new "Dancing with the Stars" Tuesday night on ABC.

Chris Hemsworth's wife Elsa Pataky was a part of cinematic history when her new movie 'Fast Five' gave Universal its highest grossing opening weekend ever for a single film, but this weekend 'Fast Five' will have to stand up against Hemsworth's 'Thor.'

At the 'Thor' Hollywood premiere on Monday night, Hemsworth told us that he made the time to congratulate his wife after the massive opening of 'Fast Five,' which pulled in over $83 million.

Perhaps some of that good fortune will rub off on Hemsworth for his big opening.

"I had a fantastic director and a great cast to support me through [the making of the film]," said Hemsworth. "It was a big collaborative effort and I had a lot of fun doing it."

'Thor' finds the arrogant Norse warrior (Hemsworth) forced to live among humans as punishment after reigniting an ancient war in his world. His true mettle is put to the test when a villainous foe sends dark forces from the realm of Asgard to invade Earth.

"I'm still reeling," said Kat Dennings, who admitted to being a "huge fan of comics" when she was younger. "I've only seen it once and I'm really excited to see it again because I cried."

'Thor' is set to clobber theaters May 6. Click the video to find out what Sir Anthony Hopkins said "makes all the difference" in Hemsworth's acting career.

The Super Bowl of fashion? According to "The Insider" host Lara Spencer, quite possibly so.

A who's who of celebrities and fashion designers were out in full force Monday night at the annual Met Costume Gala in NYC. Everyone from Gisele Bundchen to the currently controversial Donald Trump were in attendance at the plush affair that seems to have everyone dressed to kill.

This year's gala focused on a new exhibit dedicated to designer Alexander McQueen (dubbed Alexander McQueen: Savage Beauty) and his extraordinary contributions to the fashion industry, and many attendees respectfully paid homage to the late fashion icon.

"I have many great memories and I know he would be happy," supermodel Naomi Campbell gushed on the red carpet, wearing one of his vintage dresses. "To me, this day is a celebration of him."
