Slime for the camera! The Kids' Choice Awards is the only awards ceremony where stars’ glamorous outfits are practically guaranteed to get ruined — and this year’s show didn’t disappoint.

Shortly after Blake Shelton kicked off Nickelodeon’s 29th Annual Kids' Choice Awards in Los Angeles on Saturday, March 12, John Stamos became the first A-lister to get slimed as he innocently sat in the audience. The Fuller House actor, 52, was a good sport, however, as he laughed off the sticky moment after wiping his head on Jace Norman.

When Fifth Harmony took the stage to accept the award for Favorite Music Group, the five girls were also doused in gooey, green slime.

Jason Sudeikis and Josh Gad were also on the receiving end of the neon goo, not too long after they debuted a new clip of their upcoming film, The Angry Birds Movie, which also features a voice cameo from host Shelton, 39, himself!

Joe Jonas and his new band, DNCE, were lucky enough to avoid getting slimed, but they were ruthlessly toilet papered backstage by Shelton before their performance.

And the last star to get slimed was the host himself. Shelton's girlfriend, Gwen Stefani, who is in Japan and watched the show via FaceTime, even tweeted the glorious green moment.

Watch the video above to see all of the stars — including Dancing With the StarsBethany Mota and Vine star Cameron Dallas — who got slimed at the 2016 Kids’ Choice Awards!
