It was slime time in Hollywood Saturday night for Will Ferrell. The green goo, a trademark prize, was the highlight of the raucous 18th Annual Nickelodeon Kids' Choice Awards, which also starred Johnny Depp, Usher and Jamie Foxx.

"Extra" teamed up with C.J. Sanders, who played little Ray in the movie "Ray," for the orange carpet arrivals. And in addition to meeting the biggest and brightest stars of film, music and TV, C.J. even got a little advice, too.

"I'm living an example that if you believe your dreams, you can succeed," Usher told C.J.

The Kids' Choice Awards also marked a big anniversary weekend for presenters Justin Timberlake and Cameron Diaz. The couple first met at the award show two years ago.

Meanwhile, Will Smith sent fans into frenzy when he touched down on the orange carpet, and Halle Berry signed autographs for her pint-sized fans. The Oscar winner even broke some news to "Extra" about her dream role. "I want to be on 'Desperate Housewives,'" she revealed. "I am a 'Desperate Housewife,' I'd fit right in with those girls."

But Halle cleared up one rumor: she is desperate to become a mom. But is it true she's actually looking for a donor to have a child of her own? "Why, would you like to apply?" she joked.

"Extra" also put Jada Pinkett Smith on rumor control. One British paper has reported Jada would let Will cheat on her, as long as he told her. So is it true? "No, that's not true at all," Jada said. "Will's just basically saying that if he ever decided, hypothetically, to do something, I would know about it before you guys did. But it better be hypothetical!"

And big Willy, who opened the show, was among the night's big winners, nabbing the Kids Choice for favorite voice in an animated movie.

Queen Latifah was named this year's Celebrity Kids Wannabe, "American Idol" was the Kids' Choice for Best TV Show and Usher also took home top honors.

So Usher, how does this compare to all those Grammys? "There is no comparison," he replied. "Because the kids make up this one, and it's all about the kids."
