Prince William and Kate Middleton just made their final public appearance at the Darwen Aldridge Community Academy before taking their vows on April 29. It is rumored that the newlyweds will be spending at least part of their honeymoon at Balmoral Castle, a royal residence in Scotland.

Balmoral Castle was also where Prince Charles and Princess Diana spent part of their honeymoon. It was first home to Queen Victoria and is summer home to Queen Elizabeth. The Royal family has a deep history throughout Scotland, including recently where Prince William met Kate, at the 600-year-old University of St. Andrews.

The city of Edinburgh also has a number of Royal residences. Edinburgh Castle, which dominates the skyline, was a royal residence until 1603 when England and Scotland united under a single monarchy, and remains Scotland's most visited tourist attraction. On the opposite end of Edinburgh lies Holyrood Palace, built in the 15th century, which is the Queen's official residence in Scotland.

The Royal yacht, 'Britannia,' which was launched in 1953 and served the Royal family for more than 40 years until its retirement in 1997 is also docked in Edinburgh and remains a popular tourist attraction. At over 400ft in length and weighing over 4,700 tons, it has hosted four royal honeymoons and 968 total royal voyages.

"I never expected getting cut from the show [that] I would have this much support … and I'm so thankful for it," she tells "The Insider," not even realizing that she was up 30,000 followers on Twitter until after her exit. "I was in a bubble, an 'American Idol' bubble the whole time; very focused on my songs, I would never really go out – we didn't ever have that much time."

Pia says she's now focused on getting some rest and preparing for the upcoming "American Idol" tour.

Okay, so maybe it's not so surprising that John's pick to take home the mirror ball trophy is none other than his old buddy Kirstie Alley, but what is truly shocking is the amount of big-name celebs to hit the red carpet for TV Land Awards last night.

Bill Cosby, Jane Lynch, Michael J. Fox, and Stevie Wonder were all present at this year's taping. Regis Philbin will also be in attendance to receive the Legend Award, presented to him by the one-and-only Barbara Walters.  

The common theme for the night? That would be reunions! The full cast of "Family Ties," will be accepting the Fan Favorite Award, the cast of "Welcome Back, Kotter" will be honored with the 35th Anniversary Award, and "The Cosby Show" cast who will be honored with the Impact Award.

For "Cosby Show" star Raven Symone, the reunion is just about as exciting as knowing she's got a place in the network's programming. "TV Land and the Food Network were the only channels I was allowed to watch when I was growing up and knowing that I'm probably the youngest person on TV Land right now, it rocks."

Additionally, Daryl Hall and John Oates will receive the Music Icon Award and will perform some of their most popular hit songs.

The "TV Land Awards" will air on TV Land Sunday, April 17 at 9 pm ET/PT.

After tying with Hines Ward for last week's highest score, supermodel Petra Nemcova and Dmitry Chaplin are hard at work on the follow up to their highly rated waltz.

Having to perform the difficult Paso Doble this week, Petra was amused to find Dmitry's scribbled notes on how the dance should proceed. "Yesterday I discovered a paper," Petra said. "I thought it was a math exam with some doodling, and then I realized that it was actually the plan for the Paso."

When talking about why he needed to sketch the dance out on paper, Dmitry said, "It's a really difficult song to do the dance to. It's very big and very dramatic. It's going to be okay, it's a big challenge for both of us."

Adding to the challenge of the Paso Doble is the fact that all of the music this week will consist of classical songs.

Despite the challenge of a harder dance and difficult music, Petra is excited about their new routine. "The choreography looks amazing, so I'm very excited to start learning it," Petra said.

After last week's shocking sendoff for former "American Idol" contestant Pia Toscano, Will.i.am, who was featured as a mentor on the show, gave some advice for all those that have faced rejection on the program.

"Learn from why you got eliminated," said Will.i.am at the Los Angeles premiere of 'Rio' on Sunday. "Just because they say 'no' doesn't mean that's it. I got told 'no' a bunch of times. I still get told 'no.' That doesn't mean I'm going to stop."

The Grammy winner joined the long list of stars, including Tom Hanks and Ellen DeGeneres, who have offered encouragement following Pia's elimination.

Will.i.am handled the music for 'Rio' and Jamie Foxx raved about working with the Black Eyed Peas member in the studio, saying, "Sometimes your job just gives you fun things to do."

Anne Hathaway admitted that after the three years it took to make the movie, the best part of making the movie for her came at the very end: "Finally see the whole thing come together was such a gift," said Anne.

'Rio' opens in the U.S. April 15 but debuted internationally over the weekend, hauling in $55 million, which made it the biggest movie opening of this year.

Fergie's husband, Josh Duhamel, attended the American Red Cross, Santa Monica Chapter's Annual Red Tie Affair on April 9 as an honoree, and the singer gave a surprising answer to what keeps the fire burning in their marriage.

"I'm so proud, because a few tragedies have happened and [Josh] just got up and had this idea to create a run," said Fergie, referring to the Tokidoki relief run held in Santa Monica, California on March 27 that benefitted the Red Cross. "It's really attractive that [my] husband thinks of these things."

While being acknowledged for all the work he's already done for those suffering across the world, Josh urged that his job is not over yet.

"There's usually a media blitz at the beginning with something like this and then they go on to the next thing," said the actor. "Right now Japan is really hurting and I think that people should remember that."

Paris Hilton explained what sets the American Red Cross apart from the rest, saying, "There's so many charities out there but the Red Cross is one that you can really trust, and I think that's why so many people are behind it."

Betty White was also honored at the event in Santa Monica, California, and she reminisced over the charity's 100-plus years of service, saying, "Growing up, sort of the one solid, positive of my earliest memories were when anything went wrong the Red Cross was always there."
