Justin Bieber Gets Slimed At 2012 Nickelodeon KCAs!

Host Will Smith was joined Saturday (31st March) by a bevy of stars for Nickelodeon's annual slime-fest, the Kids' Choice Awards.

The movie star and rapper kicked off the night with a KCA-themed rap that included the first sliming of the night, when buckets of the famed goo fell on the audience, setting the tone for the fun-filled evening.

The Men In Black III actor promised that 2012 would include a record-breaking amount of slime, adding, "No one is safe from the slime." That included Halle Berry, who was the first celeb to get covered in green goo.

Real-life couple and The Amazing Spider-Man stars Andrew Garfield and Emma Stone presented the award for Favourite Movie Actor. But before handing the blimp to Adam Sandler, Garfield told the room: "I feel like the luckiest guy in the world, 'cause I got to play my favourite superhero."

KCA first-timer and Glee star Chris Colfer got slimed when he hit the stage to present Selena Gomez the award for Favourite TV Actress. Perhaps Heidi Klum should have shared this advice with him first: Never trust anyone at the KCAs.

Decked out in a two-piece, midriff-baring top and sparkly skirt, Gomez also won for Favourite Female Singer. "After no longer doing my show, knowing you guys still watch it means so much," she said of her now-defunct Disney series The Wizards of Waverly Place.

Perry also won a blimp for her work in The Smurfs, declaring, "The only reason I'm here today is because I've never gown up. I can't wait to do Smurfs 2."

Kristen Stewart won for Favourite Movie Actress for The Twilight Saga: Breaking Dawn - Part 1. Beaming in blue lace, she said: "This is, like, the coolest awards show ever. I love Nickelodeon. I liked Doug, Rocco's Modern Life.'Awesome. I just have to say: Katy Perry's armour was the coolest thing I've ever seen."

Next up, the show got a bit serious when first lady Michelle Obama presented Taylor Swift with the Big Help Award. Swift won the special blimp in recognition of her philanthropic efforts, including work with U.S. tornado and flood survivors and various youth-related charities.

Taylor Lautner has kicked enough butt and taken enough names on the big screen that he won the blimp for Favourite Butt Kicker.

"This is amazing," he told the room of screaming fans. "Robert, I'm sure you'll be winning this award next year for Iron Man 3 and The Avengers." That Robert he was referring to was presenter Robert Downey Jr., not Pattinson, obviously.

After winning, he was forced to do 1,000 push-ups by Smith. His reward for completing the mission? Getting slimed.

Proving that everyone is a One Directioner at this point, Katy Perry, Taylor Swift and Selena Gomez danced around in the audience and sang every word of the song, while the five-some kept girls screaming with their frothy, lighthearted pop track.

Jaden and Willow Smith were then on hand to present the night's last award for Favourite Male Singer, with Justin Bieber - who was fresh from shooting his Boyfriend video - taking to the stage to accept his blimp.

The 18-year old stated: "Right now, I've been working really hard on my album, Believe. This album is our album. This [blimp] goes out to all the fans. I love you so much,"

In addition to the gong and with Will by his side, Bieber got über-slimed, with the ooey-gooey stuff spewing out from the stage all over him. And, with that, the show ended.
