Watch Kristen Stewart, Justin Bieber and Others Read Mean Tweets About Themselves

Twitter is a double-edged sword: the direct, unfiltered nature of the social networking site allows people to more or less talk directly with (or directly at) celebrities, which can mean fun fan interaction or horrible, horrible insults.

Jimmy Kimmel knows this, so on a recent episode of "Jimmy Kimmel Live!" he had a number of celebrities sit down and read some of the awful, instulting tweets that people send to them. The result is a pretty hilarious montage of the likes of Katy Perry, Danny McBride, Matisyahu, Zooey Deschanel, Snooki and Kristen Stewart reading some truly terrible stuff.

Highlights include one Twitter user hoping that God will take back Justin Bieber and give us 2Pac, Matt LeBlanc telling a tweeter "go f*ck yourself" for saying he looks old, and Kristen Stewart adjusting her imaginary (we hope) balls.

The winner, though, might be David Spade, whose Twitter enemy "got right to the point."
