He may be 18 now, but Justin Bieber is still a kid at heart, and he got slimed Big Time at the 25th annual Nickelodeon Kids Choice Awards on Saturday night.

In case you are wondering who is holding him in place, that would be host Will Smith, making sure that he did not get away.

I am just hoping that Justin was not wearing his $65,000 diamond encrusted Stewie necklace. He would have a heck of a time getting all of that slime off of it! But, all was not lost, Justin walked away with a Fan Choice Award. Congrats to you, and  make sure to stay tuned to Mix 108 for Justin's hot new song "Boyfriend."
