Brody Jenner, Avril Lavigne

Avril Lavigne and Brody Jenner say they were injured outside of a Hollywood bar in the middle of a brawl.

"I got attacked by 5 people last night out of nowhere. Not cool. My face is f——ed," Lavigne, 27, tweeted. "As in black eye, bloody nose, hair ripped out, scratches, bruises and cuts. So not ok to be abusive to others. Violence is NEVER the answer."
