The four times platinum singer reportedly got into a scuffle with an unidentified woman at the Hollywood Roosevelt Hotel at one in the morning over the weekend.
When Kim Kardashian's step brother and Avril's boyfriend tried to break it up between the two girls, he got smashed in the head with a bottle! He was rushed to the hospital and needed some stitches.
He later tweeted about the fight saying, "Interesting Saturday night... Just got of the hospital with a new scar on my face.. Charges/chargers!!!"
Avril also took to Twitter to give an update to her friends and fans.
"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 fu**ed. 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."
Let's hope we these two don't get into anymore fights any time soon! Check out the exclusive pictures from our friends at X17Online.
