The Nickelodeon Kids' Choice Awards roll into LA this Saturday, and we're getting ready by taking a look at the show's most memorable photos. Kids' Choice is always a fun event, and a great chance to see some of our favorite celebs with young family members.

There are many iconic moments from the ceremonies over the years. Britney Spears had a famous backstage run-in with Brad Pitt, and the Destiny's Child girls, including Beyoncé Knowles, revealed their abs in matching costumes. Johnny Depp even had an opportunity to be in the slimelight. Click through now to see all the exciting pics from past shows.

Rachel Zoe hit the black carpet in LA last night to celebrate Valentino's 50th anniversary at its shop on Rodeo Drive. She stopped for a moment to say hello to pal Molly Sims, who covered her growing stomach in a long black gown. Molly, who married producer Scott Stuber in September, is six months pregnant with her first child. She and Scott expect their first bundle of joy to arrive in June. Molly and Rachel shared space on the carpet with a Lela Rose-clad Kim Kardashian, as well as other starlets like Jessica Stroup, Jessica Szohr, and Ciara. Rachel is a well-known Twilight fan, but she took a second to say hello to an actress from another major movie franchise. The Hunger Games' Isabelle Fuhrman caught up with Rachel Zoe at the dinner, and the young actress later tweeted that she was "so happy to have met such amazing people" at Valentino's event.

Adriana Lima held hands with her husband Marko Jaric last night as they headed into an event hosted by the Brazil Foundation Gala at the W Hotel in South Beach. The supermodel attended the Miami bash in support of her home country, and headed inside for a dinner with other famous Brazilians like racecar driver Helio Castroneves, model Isabeli Fontana, and Marc Jacobs's on-off boyfriend Lorenzo Martone. Lorenzo and Isabeli emceed the soiree, which raised $72,000 for the organization.

There was an additional reason for Marko and Adriana, who have been married for three years, to celebrate. It was confirmed last week that Adriana Lima is pregnant with the couple's second child! They're already parents to 2-year-old Valentina. In a statement, Adriana said, "The entire family is very excited, especially Valentina. She keeps blowing kisses to my belly and saying, 'Kisses for the baby.'"

The gang from Battleship dressed up today for a photocall on behalf of their Summer blockbuster at London's Corinthia Hotel. Brooklyn Decker donned a Stella McCartney dress that is a celeb favorite — Gwyneth Paltrow wore it to an event in China, while Sienna Miller donned it on a recent British Vogue cover. Rihanna was decked out in a silky dress and Taylor Kitsch looked hot in a suit.

The long promotional road is just starting for the trio ahead of the film's release on May 18. Brooklyn, though, has already been making the rounds for nearly a week. She and Taylor were in Hamburg, Germany, a few days ago, along with director Peter Berg. Brooklyn was also in LA for WonderCon, and attended a panel with the movie's other leading man Alexander Skarsgard. Between all the work, Brooklyn's found time to shop. She recently tweeted a photo of her idea of heaven, the candy selection at Harrods!

2012 is the year of Snow White. There are currently two different films on their way into the theater based on the classic fairy tale: Universal's Snow White and the Huntsman, due June 1, 2012, and Relativity's Mirror Mirror, which is scheduled to open this weekend. As they've come together, it's been tough keeping up with the separate films and trying to not get them confused, so I'm helping you out. Check out who's who in each movie now before you see them and have the chance to determine which movie is the fairest of them all.

Kate Winslet ruled the red carpet at this evening's London premiere of Titanic 3D, held at the Royal Albert Hall. She posed for pictures alongside the movie's director, James Cameron, who's fresh off an exciting adventure. He was near Guam just a few days ago, setting a deep-sea record exploring nearly seven miles under the Pacific Ocean. Kate's main man from the iconic film, Leonardo DiCaprio, skipped out on the event. However, she had the company of another costar, Billy Zane. Even Kate's boyfriend, Ned Rocknroll, was seen sneaking into the theater for the screening. Ned has been by Kate's side for the last few weeks as she jetted around the world talking up the rerelease of Titanic.

On her way into Royal Albert Hall, Kate spoke about seeing Titanic 15 years after it was first released. She said, "[It's like] a home video. It’s like saying, 'We’re going to show three and a half years of your life, live to the Albert Hall!'"
