Pitbull and Christina Aguilera had a goo night at the Nickelodeon Kids’ Choice Awards…

The 32-year-old Cuban American rapper and 32-year-old half-Ecuadorian American singer opened up the network’s annual awards show with a performance of their hit single “Feel This Moment.”

“Excited to be on stage performing with @Pitbull. Wonder who will get slimed? #KCA,” the four-time Grammy winner tweeted to her 3.9 million followers before the show.

Pitbull and Aguilera, who saw their dancetastic single rise to No. 11 on the Billboard Hot 100 chart this week, were joined by 20 young backup dancers who resembled them to a T.

And at the end of their high-octane performance, Aguilera spushed the “slime” button, covering Pitbull and the dancers in the show’s signature green goo.

After leaving the stage, Pitbull immediately tweeted a picture of himself backstage still covered in the green gunk.

“daleeeeeeeeee #KCA #SLIMED,” wrote the rapper.
