Host Josh Duhamel jumpstarted the 2013 Kids' Choice Awards with a cover of Pitbull's "Don't Stop The Party," getting in a food fight with Megan Fox, having a sing-off with Aerosmith's Steven Tyler (he lost) and impersonating a pregnant Fergie. But the real Pitbull quickly showed up to take over the show, and he brought a special friend along.

Christina Aguilera emerged from scaffolding in black fedora, high-waisted pants and suspenders to belt out their latest collaboration, "Feel This Moment." And if one Christina wasn't enough, 10 other kids sprouted from the aisles, all dressed like the diva. That's right: 10 fedora-rockin', blonde-wig sportin' miniature Aguileras... and they were great backup dancers. Pitbull got his mini-mes too when a bunch of energetic kids pop-locked it behind the stars in bald caps and dark sunglasses.

Sunbursts of neon circled behind the performers, and for a grand finale, Nick's signature green slime spurted from the stage, fountaining over the singers and the kid versions of themselves. Pitbull wallowed in the KCA glory, not letting the green gook stop his party attitude.

Ke$ha is set to perform later in the night, who, coincidentally, just announced a tour with Pitbull, beginning May 23. Will she get slimed too? Watch to find out!
