Avril Lavigne sustained several injuries when she was involved in a brouhaha at the Roosevelt Hotel in Hollywood on Saturday night (November 6th).
Her boyfriend, Brody Jenner, was injured as well, after he tried to intervene and got struck with a bottle on his head.
Lavigne took to her twitter account to clear the air on the brawl, tweeting, "I don't fight. I don't believe in it. To clear things up I got attacked by 5 people last night out of nowhere. Not cool. My face is fucked."
She continued: "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."
As to what sparked the melee, and who it was with, that isn't yet known.
