Avril Lavigne and Brody Jenner involved in Hollywood bar brawl: Report

Canadian singer Avril Lavigne and her reality TV star beau, Brody Jenner, were reportedly involved in a bar brawl late Saturday night. Jenner, famous for wooing Lauren Conrad on MTV's "The Hills" (and for having those infamous Kardashians as stepsisters), had his head split open with a bottle during the fight. He later took himself to the hospital.

A source told E! News that Jenner was hit with the bottle by a woman at the Hollywood Roosevelt Hotel when he tried to break up an altercation between her and Lavigne. What is this, the Wild, Wild West?

Police arrived at the hotel, but were able to speak only to Jenner because, according to TMZ, Lavigne and the other woman had already left. The police report listed Jenner as "the victim of an assault with a deadly weapon."

Jenner took himself to the hospital. The Kardashians' stepbrother later tweeted, "Interesting Saturday night... Just got of the hospital with a new scar on my face.. Charges/chargers!!!"
