It was a messy, messy night at the 25th Annual Kid's Choice Awards.

The annual awards show is known for sliming the celebrity attendees with green goo.

Halle Berry was the first star to get slimed -- from her seat in the audience! Taylor Lautner, Chris Colfer, Justin Bieber and even host Will Smith were doused, much to the audience's delight.

First Lady Michelle Obama (looking chic in a modern, metallic-colored outfit) presented Taylor Swift with a special "big help" award for her charity work.
