Slime time!

The 2018 Kids' Choice Awards kicked off on Saturday, and it was slimier than ever!

Kids' favorite stars headed to the Forum in Inglewood, California, to dole out and collect awards -- but not without getting slimed first. 

Celebs like Heidi Klum, Mel B, Shawn Mendes, JoJo Siwa and more were the chosen ones this year, getting hit with a face full of slime during the awards show. Check out the hilarious moments below. 

First up was YouTube star Liza Koshy, who barely got through her acceptance speech after winning Favorite Funny YouTube Creator before slime cannons erupted with green goo. 

Then came Klum and Mel B, who were perfectly primped in show-stopping ensembles before the Nickelodeon team decided a little green would do their outfits good. 

Poor Shawn Mendes couldn't even make it to the show, but that didn't stop him from getting slimed while accepting his award for Favorite Male Artist. 

And what better way for JoJo Siwa to end a performance than with a big finish? 

Last but not least, there was host John Cena, who couldn't help but admit he brought this upon himself.
