Canadian singer Avril Lavigne and her boyfriend are recovering after being attacked outside of the Roosevelt Hotel in Hollywood in the early hours of Sunday.
Celebrity news website TMZ said five people had attached Lavigne and The Hills star Brody Jenner outside of the iconic Hollywood hotel.
Lavigne, 27, addressed the incident on Twitter.
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, Lavigne posted, adding that she had suffered a black eye, bloody nose, hair ripped out, scratches, bruises and cuts.
So not ok to be abusive to others. Violence is NEVER the answer, the singer said.
Jenner, 28, who is also the step-brother of the Kardashian siblings, posted about the incident on Twitter, saying Just got of the hospital with a new scar on my face.
No arrests have been made in connection to the incident, although a spokesman for Los Angeles Police Department said they were aware of a skirmish outside in that area on Sunday morning.
Lavigne's representatives were not immediately available for comment.
