Kids Choose Miley, Johnny, Jessica

You don't have to be a kid to win big at the Kids' Choice Awards, but it certainly seems to help.

Just ask Miley Cyrus, who enjoyed the best of both worlds—singing and acting—at Nickelodeon's 21st annual slime fest Saturday night, taking home awards for both Favorite TV Actress and Favorite Female Singer at the kid-powered show.

The omnipresent Hannah Montana star, who also performed her new single "G.N.O.—Girl's Night Out" during the ceremony, was the only individual double winner of the night.

The night's only other multiple honoree was Nickelodeon's homegrown talent Drake & Josh, which not only took home the coveted orange blimp for Favorite TV Show, but earned series star Drake Bell the Favorite TV Actor award, as well.

Jack Black returned as host, opening the night with one of his trademark musical parody numbers—this time around a rousing rendition of "I Was Made for Sliming You," an ode to the wonders of the show's signature green goo—before welcoming the tween masses to "the slimiest, starriest, choiciest awards show ever!"

The first prize of the night went to Jessica Alba, who was crowned Favorite Movie Actress at the completely fan-determined awards show. As Black was keen to boast, more than 88 million votes were cast prior to the ceremony.

But for all the awards doled out over the course of the show—perpetual favorite Johnny Depp took home the nod for Favorite Movie Actor, though parents can rest assured it was for swash-buckling turn in Pirates of the Caribbean: At World's End rather than the blood-soaked Sweeney Todd, while Alvin and the Chipmunks was honored as Favorite Movie—slime was definitely the name of the game.

In keeping with the green theme, Heidi Klum gamely made an appearance at the show, coming onstage to pop slime-filled balloons with help from a giant bum-spanning pad covered in spikes. Usher and Akon got in on the messy action later in the show, blasting a sumo wrestler with an industrial strength slime hose and making their way through a slime-filled obstacle course, respectively.

The slimey set pièce de résistance, however, came courtesy of host Black and Orlando Bloom, whose climactic and lengthy joint sliming was one for the show's history books.

In a change of pace, the awards show also managed to make history for another, completely slime-unrelated reason: The distribution of the first ever Wannabe Award.

Cameron Diaz was the honored recipient, so chosen for being the celebrity kids most "want to be." Ashton Kutcher was on hand to present the award.
