Avril Lavigne, Brody Jenner Tweet About Bar Brawl

'I got attacked by 5 people last night out of nowhere. Not cool,' Lavigne writes.

Avril Lavigne and her boyfriend, former "Hills" star Brody Jenner, were reportedly in a bar scuffle over the weekend in Los Angeles. Jenner was injured while trying to break up a fight at the Roosevelt Hotel, according to TMZ.

The fight took place early Sunday morning between an unknown woman and Lavigne. The site reported that law enforcement sources say that hotel security broke up the altercation and that Jenner and several others were detained. Police have listed Jenner as a victim in the scuffle. Also according to the report, Jenner was the only one involved who spoke to police; Lavigne and the others had already left by the time investigators arrived.

The site also posted a photo of Jenner sporting a head injury. Both Jenner and Lavigne addressed the reports on their respective Twitter accounts.

"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 f---ed," Lavigne 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."

Jenner also used the social networking site to open up about his injuries. "Interesting Saturday night ... Just got of the hospital with a new scar on my face. Charges/chargers!!!" he wrote.

In a tweet posted before the fight, Jenner seemed more optimistic about his time hanging out with Lavigne. "Having the best night with the love of my life @AvrilLavigne so happy right now!! ... #Movember CRUSH!! Haha," he wrote, tweeting a photo of himself with Lavigne.

When contacted by MTV News, reps for the LAPD and the Roosevelt had no further information on the report. Reps for Jenner and Lavigne had not responded to MTV News' requests for comment by press time.

On Monday morning (November 7), Lavigne seemed to be nursing her wounds. "Thank you @EvanT for coming over to visit me today and bringing me a hello kitty ice pack. I'm so lucky to have a friend like you," she said in an update.

This isn't the first time Jenner has been in a highly publicized bar fight. Back in August 2009, Jenner and then girlfriend Jayde Nicole got into a bar fight with "Girls Gone Wild" creator Joe Francis.
