Justin Timberlake made sure last night's (31MAR07) Nickelodeon Kids Choice Awards were a messy affair when he became one of many celebrities to get 'slimed' at the Los Angeles prizegiving. The pop superstar hosted the awards, and although he boasted he was too famous to get slimed in his opening song, the SEXYBACK star was covered in the event's famous green goo twice. Mandy Moore, Rush Hour stars Chris Tucker and Jackie Chan, SPIDER-MAN TOBEY MAGUIRE and Steve Carell were among the other stars to get messed up at the show, while Timberlake and Vince Vaughn ended the show with a slime fest - both got hit with the green stuff and then turned the goo on the audience, hosing down kids and their parents. Timberlake was also a big winner on the night, claiming the Best Male Singer prize. In receiving his award from late CROCODILE HUNTER star Steve Irwin's daughter BINDI, the singer heaped praise on the thrilled Aussie, stating, "This young lady will change the world." But he was also a big loser - he gave up his 2006 Celebrity Burp Champion of The World belt to the 20,000-strong Kids Choice Awards audience, who belched louder and longer than he did. Among the night's other big winners, Beyonce Knowles took home the Best Female Singer prize and the Best Song honour for IRREPLACEABLE, Adam Sandler and Dakota Fanning claimed the event's Best Movie Actor and Actress awards, and Spongebob Squarepants picked up the Favourite Cartoon prize for the fifth successive year. The winners were: Favourite Movie Actress - DAKOTA FANNING Favourite Music Group - Black Eyed Peas Favourite TV Show - American Idol Favourite Voice From An Animated Movie - Queen Latifah (Ice Age: THE MELTDOWN) Favourite TV Actor - Drake Bell (DRAKE + JOSH) Favourite Animated Movie - HAPPY FEET Favourite Movie Actor - ADAM SANDLER Favourite Male Singer - JUSTIN TIMBERLAKE Favourite Female Singer - BEYONCE KNOWLES Favourite Song - IRREPLACEABLE by BEYONCE KNOWLES Favourite Cartoon - SPONGEBOB SQUAREPANTS Favourite Movie - Pirates Of The Caribbean: DEAD MAN'S CHEST Wannabe Award - Ben Stiller.
