Ralph Macchio displayed impressive athleticism as Pat Morita's protégé in 'The Karate Kid' but that was over 25 years ago, so how has the former martial arts prodigy faired through his "Dancing with the Stars" rehearsals so far?

"My body is holding up," said Macchio. "It's a crash course in using muscles, tendons, ligaments and joints that have been sleeping for 25, 30 years and they're like, 'Yo, what is up?'"

Macchio admitted that the process of turning himself into a dancer has been painful, saying, "I'm sore. I had a little strain in my inner thigh yesterday so I spoke to someone on how to sort of ice that on and off and prevent that from becoming a bigger problem."

The former child actor said that he's found encouragement from his family, who has been pushing to join the program.

"My wife just said, 'You must do this,'" said Macchio. The ballroom contender also has an 18-year-old daughter and a 15-year-old son, whom he said "are really rallying behind it."

Macchio also has an encouraging dance partner, Karina Smirnoff, whom he seems to get along with.

"We laugh an awful lot," Macchio said.

Karina said that she didn't think they were ready for the competition yet but that they're in a "good place to start fine tuning everything and bringing everything together and hopefully by [March] 21 the package will be ready."

Be sure to tune in to the season premiere of "Dancing with the Stars" Monday, March 21 on ABC.

Entertainment Tonight was able to show you police knocking on Charlie Sheen's front door. After entering the estate through a side entrance, police shook hands with who appears to be the actor on his property.

A source tipped off Entertainment Tonight just before police arrived, allowing ET to capture this exclusive video of the very first moments between Sheen and LAPD officers.

Charlie Sheen's divorce and custody lawyer Mark Gross spoke outside of the actor's Mulholland Estates home late Thursday night.

"The LAPD executed a search warrant, which they had issued pursuant to the fact that there's a temporary restraining order which was issued on March 1, 2011, which among other things precludes Charlie from having guns in his possession," Gross said. "Somebody made some statement apparently to the LAPD, a reckless statement, about something with Charlie and guns. They properly did their job. They did an investigation and, as a result of that investigation, a warrant was issued."

He praised the authorities for "officially, appropriately, professionally, courteously, and thoroughly" executing the warrant. "The only thing that they took with them…was a few bullets and a 1800s antique gun," he announced. "They've taken them in their possession and Charlie will get them back in his possession at the appropriate time. But other than that, they didn't seize anything. Someone had asked if they found any drugs. The answer is absolutely not."

Gross described Sheen's demeanor as "calm" during the LAPD raid. He also acknowledged "yapping on the internet" surrounding a 5150 hold, which "is an involuntary psychiatric hold." Squashing the rumors, Gross added, "Anybody who's saying that, anybody who's implying that, couldn't be more wrong."

The attorney "doesn't expect" Thursday night's police search to result in a court appearance. "The only consequence there could be would be related to the [temporary restraining] order and we'll just deal with that in due course," he said.

Six-year-old Eden Wood has made her mark on the beauty pageant world, being known as a feared competitor, but Eden's mom Mickie says that pageants are just the beginning.

"Pageants gave us a start, but Eden is so much more than just a little pageant girl," said Mickie. "Pageants were kind of a means to an end."

After gaining confidence by spending hours in front of pageant judges, Eden now has so much stage presence and experience that she has branched out into a music career and "The Insider" gained access to the Iowa shopping mall where Eden shot her first music video.

Little Eden sang a song called "Cutie Patootie" for screaming fans in a crowd of children and adults.

In spite of all the attention she's getting, Eden manages to stay grounded.

"She's such a nice girl," said pageant mom Kelly Smith. "She's the furthest thing from snooty."

Eden hails from Arkansas but while in Iowa she stopped by the Blank Children's Hospital to hand out toys to the patients there.

Watch the video to see Eden launch her singing career, shooting her new music video. "Toddlers & Tiaras" airs Wednesdays on TLC.

Teachers have a difficult job, making sacrifices for the sake of their pupils, but in Cameron Diaz's new movie 'Bad Teacher' it's the students who suffer.

In the movie, Elizabeth (Diaz) couldn't care less about her job teaching grammar school and she does little to hide it. When a rich, handsome substitute (Justin Timberlake) joins the school, Elizabeth sets all of her focus on manipulating him into marriage, going to extremes that cause her to gain a new perspective on herself and the way she's been living her life.

'Bad Teacher' opens June 24.

The Insider interviews "American Idol"'s Top 13 contestants right after their performances on Wednesday night's show! The FOX music hit is heating up with the remaining contestants fighting hard to stay in the competition.

Naima Adedapo, 26, who made it into the Top 13 as a wildcard, says she was excited to give viewers what they haven't seen before: "I know I felt pretty good, I can't say that I didn't. I know that I had my issues during my performance, but to be able to bring the reggae/dance hall style to the stage and kind of put some 'American Idol' history in there, I'm happy about that, you know what I mean, because nobody's ever done it on the show before and I'm excited about that." Naima even shows us some of her dance moves that received rave reviews!

Twenty-three-year-old Jacob Lusk could barely contain his excitement: "It felt absolutely amazing. I mean it's a dream come true. Not only were we singing our idol's songs, but we worked with Jimmy Iovine, and for me personally I worked with Rodney Jerkins -- a super producer -- on a super song, on a super stage, in a super year, it's just absolutely bananas."

When asked about his "dance off" with host Ryan Seacrest, "Idol" hopeful Paul McDonald, 26, said he came out on top: "He doesn't quite have the moves that I have, you know. He can practice all he wants but he can't hang with all this."

Wildcard contestant Stefano Langone, 21, said he was just thrilled to be on the "Idol" stage: "Honestly it was just an honor to do your idol song on the biggest stage in the world. And then when you get to work with the people we got to work with this week, I'm mean it's really just an honor and a blessing and I think we all went out and just, we killed it tonight."

Kelly Preston is such close friends with Kirstie Alley that Kirstie was actually present while Kelly gave birth to her youngest son Benjamin last year, and Kelly supported her buddy at the opening of her first Organic Liaison store on Wednesday, dishing about her newborn.

"Oh my gosh, he's so cute," said Kelly. "He gets cuter every single day."

Benjamin already shows signs that he's taking after his father John Travolta. Kelly called her little boy "a natural born flyer."

"He's had now -- because we just came here last night -- four flights already at three months old," said the actress. "He got up in the cockpit with Daddy a few times, too."

Kirstie, who referred to Kelly as "the quintessential mother," dished about her own "baby" - Organic Liaison.

"I tell people it's what's not in it that's good," said Kirstie. "It's the first USDA certified organic weight-loss product and it gives you incredible energy. I would never be able to do what I'm doing without this."

Currently, Kirstie is "doing" "Dancing with the Stars," competing on the reality show with her pro dance partner Maksim Chmerkovskiy.

"It's crazy hard," Kirstie said of "DWTS." "It's lunacy. It just takes so much energy and so much stamina."

Along with her demanding rehearsals, Kirstie is also busy losing weight. The new ballroom warrior has lost 60 pounds and hopes to drop another 30.

Kirstie expressed plenty of enthusiasm about working with her dancing partner so far, so could there be another romance brewing in the "Dancing" studio?

"[Kirstie] calls me Daddy," Maksim told us on Wednesday night.

Kirstie admitted, "He's fun," but the actress went on to clarify, calling their relationship "siblingesque."

Make sure to catch Kirstie and Maksim on the 12th season premiere of "Dancing with the Stars" on Monday, March 21 on ABC.
