Kelly Osbourne owned the orange carpet at the 2012 Kids' Choice Awards. We've never seen the 27-year-old E! fashion correspondent look this amazing!

Ozzy's little girl, still sporting light purple hair, was wearing a frilly black Tony Ward dress, Giuseppe Zanotti heels and jewels by Arunashi.

That's the way to rock an LBD! Check out more arrivals in the video below.

When it comes to arriving in style, the Smiths know how to do it right!

Jada Pinkett Smith and kids Willow and Jaden walked the red carpet at the Kids' Choice Awards in three very distinct looks. And yes, we're talking high-priced designer duds ... even for the kids!

Will's 40-year-old wifey chose a fuchsia silk cap sleeve Catherine Malandrino jumpsuit with jewels by Kimberly McDonald. It's Hammer time, Jada!

As for her 11-year-old daughter Willow, the pink-haired cutie rocked a Chanel dress, custom Chanel boots and a vintage motorcycle jacket. Jaden, 13, wore a custom vintage motorcycle jacket and boots ... both by MCM.

Papa Will got slimed during the Kids' Choice Awards along with Jaden's bud Justin Bieber. Can't wait to see footage of that green mess!

Ashley Tisdale is a red hot mama!

Although she looks a bit like Christina Aguilera from the 2003 "Come On Over" video (pink streaks and all!), the Tis definitely didn't disappoint while hitting Nickelodeon's orange carpet.

The former High School Musical starlet, who smiled while waving to her fans, wore a flowy red gown with just a touch of black and white underneath.

All those hours at the gym have definitely payed off for the Tis. She's sexy and we ALL know it!

Ms. Tisdale's rock star beau Martin Johnson is one lucky dude!

Heidi Klum posed for pictures at the 2012 Nickelodeon Kids' Choice Awards at the USC Galen Center in Los Angeles this evening, and no offense to Selena and some of the other lovely ladies in attendance, but the 38-year-old supermodel put them to shame with her boots and dress combo.

While showing your stomach is always a surefire way to get everyone's attention, Heidi knows that showing the right amount of skin is what matters the most.

Kristen Stewart posed for pictures at the 2012 Nickelodeon Kids' Choice Awards this evening, and she looked absolutely stunning in this blue lace Stella McCartney dress.

It also seems like this was her lucky outfit, as she walked away with the award for Favorite Movie Actress award for her role as Bella in The Twilight Saga: Breaking Dawn – Part 1! While accepting her award, Kristen admitted that it was her first time at the KCAs, adding, "This is, like, the coolest award show ever."

What happened to the nervous slash awkward starlet who dropped her MTV Movie award a few years ago?!

Emma Stone is a stunning beauty, so no need to wear something daring!

The Help star, who arrived at the Kids' Choice Awards with sexy beau Andrew Garfield, walked the red carpet in a simple Antonio Berardi top and skirt, Alejandro Ingelmo shoes, a Fendi bag and jewels by Irene Neuwirth.

We're lovin' the 23-year-old starlet's blonde locks!

Emma and Andrew presented together during the show. Of course, Will Smith had fun introducing them ... referencing their film The Amazing Spider-man. Sounds web-tacular!

Katy Perry's tight tummy has us green with envy!

The "Part of Me" singer walked the orange carpet at the 2012 Kids' Choice Awards in a slime green-colored top, skirt and matching heels. No one can deny, the 27-year-old songstress looks sexy and fierce ... even with the long purple and blue ponytail!

Ms. Perry, who won an award for Favorite Voice from the movie The Smurfs, was also up for Favorite Female Singer. But no fireworks for Katy! Selena Gomez walked away with the award.

Wondering when Katy's going to ditch the funky hair and get back to the basics? We know girls just want to have fun, but that blue hue could use a touch up!

Will Smith hosted the 25th annual Nickelodeon Kids' Choice Awards tonight, and not only was there plenty of green slime, but some of our fav celebs walked away with the top prizes!

Selena Gomez won for both Favorite TV Actress and Favorite Female Singer, and her beau Justin Bieber snagged the award for Favorite Male Singer. Selena showed quite a bit of skin in this Dolce & Gabbana dress, and while it's a pretty floral print, it seems a bit er, skimpy for younger audience, doesn't it? Then again, she has been in a bikini filming Spring Breakers for the past few weeks, so maybe that influenced her fashion this evening...

Kristin Stewart won for Favorite Movie Actress while her Twilight co-star Taylor Lautner went home with the prize for Best Butt Kicker, and Katy Perry was given the award for Favorite Voice From An Animated Movie for her work on The Smurfs.
