It was pure pandemonium in Los Angeles yesterday as Nickelodeon's 26th annual Kids' Choice Awards took place yesterday and almost all of Hollywood was there for the big show!

Kristen Stewart, Jessica Alba and a host of other celebs put their best foot forward on Saturday strictly for the kids and some even walked away with an orange blimp, including K-Stew who took home two for her roles in The Twilight Saga: Breaking Dawn - Part 2 and Snow White and the Huntsman.

Check out our gallery below to see who showed up and see the full list of winners after the jump!

We like the executive look!

Jennifer Garner was all dressed for business on Friday as she ditched her usual attire for a white dress shirt, black pencil skirt, and high heels while meeting up with a friend in Los Angeles.

The 40-year-old mother of three was without her hubby Ben Affleck and their brood, presumably taking care of things career wise.

Don't lose this look Jen!

She's not afraid of a little color!

Alessandra Ambrosio was far from bashful with her fashion choice on Friday, wearing a bright blue print dress with some friends while out in Brentwood.

The 31-year-old model has been on a media blitz to help promote Victoria's Secret's new lingerie line alongside fellow Angels Candice Swanepoel and Karlie Kloss.

Looks like she found some time to unwind!

Guess he didn't have a game last night!

Last night, Kris Humphries and some of his pals squeezed in a night on the town in Los Angeles as they hit up a new hotspot Aventine in Hollywood.

The Brooklyn Nets player was a no-show at Kim Kardashian's nine hour deposition earlier this week due to basketball obligations but is adamant on arriving in town for the big trial on May 6, even if it conflicts with the NBA playoffs.

It'll be interesting to see how this all plays out!

Nothing like treating yourself to a shopping trip!

Yesterday, Hilary Duff decided to let her hair down as she hit the streets looking relaxed to stroll through some stores in Beverly Hills.

The 25-year-old actress has been all about her baby boy Luca lately and after celebrating his first birthday earlier this week, some alone time seemed to be in her sights.

Sometimes retail therapy is all you need!

Well, not the entire country!

On Friday, Orlando Bloom did a bit of sightseeing during some down time in Istanbul, taking in the many of the locals sights including the Blue Mosque, Hagia Sophia Museum, and the Yerebatan Water Cistern.

The 36-year-old actor has been in the heart of Turkey since earlier this week as he's gearing up to shoot his new film Cities, a thriller that connects three different stories revolving around the Dow Jones nearing an all time high from three different locales, London, Mumbai, and New York.

Even when he's vacationing he's working!

Eva Mendes might be madly in love with boyfriend Ryan Gosling, but that doesn't stop her from turning heads!

On Friday, the 39-year-old actress looked absolutely gorgeous in a cute red cheetah print dress as she smiled for photos while outside the Late Show with David Letterman studios.

The Place Beyond the Pines star's been on her press tour for her new flick but has also had one foot in the fashion world as she's collaborating with New York & Company to start on her own clothing line, hoping to have it in stores for the fall.

Can't wait to see what designs she has in store!

This is the first time we've seen them being affectionate!

Britney Spears and her new boyfriend David Lucado have stepped out a couple times together since they began dating, but we've never seen the pair acting like a couple until now!

The pop princess and her new beau held hands as they left the mall in Thousand Oaks today, and David looks like he only has eyes for Brit Brit!

The Grammy winner donned a pink and black dress, and just when we were about to give her some serious style points, we saw her awful brown shoes. Yuck! Her legal intern sweetheart didn't look much better in jeans, a tight vest, and a baseball cap. When you're dating the world's most famous singer, you might want to step up your game, Mr. Lucado!

We wonder what ex-fiance Jason Trawick thinks about his lady love moving on so quickly after their break-up?

We haven't seen the mother-of-two this happy in a while, so this new guy must be doing something right!
