Justin Bieber Gets Slimed!

Justin Bieber was absolutely COVERED in green slime at the Nickelodeon's 25th annual Kids' Choice Awards!

We've never seen him look so shocked before.

To be fair, he had due warning. Will Smith, the host of the awards show, warned every single celeb in the star-studded audience that the goo was a very real threat:

"No one is safe from the slime."

The singer, who won Favorite Male Singer, joined Smith on stage to accept his award. He looked mighty chuffed about it too, until Will Smith ducked behind him.

Cue the biggest slime blast ever - it barely missed First Lady Michelle Obama! We bet it'll take the 'Boyfriend' singer weeks to get all of that out of his glossy locks... at least he can go home to girlfriend Selena Gomez.

But the Bieber wasn't the only one to get doused in the green stuff; Halle Berry got a bucketful as she sat innocently in the audience, while Glee's Chris Colfer got caught off guard with a blast while presenting with Heidi Klum.

And ab-tastic Taylor Lautner received his dousing after picking up the trophy for Favorite Butt-Kicker.

It's tough being a celeb, huh?
