Taylor Swift thinks Justin Bieber and Selena Gomez should get a room.

Taylor, who won 8 awards at Sunday night's Billboard Music Awards, was walking backstage when she saw Justin Bieber kissing Selena Gomez. She was was so disgusted at their behavior that she wrinkled her nose and stuck out her tongue.

Watching them kiss made her feel like she was doing something illegal.

That wasn't the only action at the awards where Bieber was concerned.  He was booed as he accepted the Milestone Award. which is an award voted on by the fans.  The boos were mixed with cheers though.  He was hesitant to speak at first  When he did, he said "It should be about the craft, the craft that I'm making."
