Kim Kardashian's brother was attacked by at least 5 people in a barfight last saturday and was horribly injured along with Rockstar Girlfreind Aviril lavine ....

Avril Lavigne is on the mend following an attack in L.A. early Sunday (Nov. 6). Lavigne's boyfriend, Brody Jenner (of MTV's "The Hills" fame) reported to police that he was hit with a smashed bottle outside the Hollywood Roosevelt Hotel, while Lavigne detailed her injuries on her Twitter account.

Los Angeles police Sgt. Keith Green said Monday (Nov. 7) that Jenner filed a police report of assault with a deadly weapon after being hit.

According to Lavigne's Twitter, she was "attacked by five people last night out of nowhere... My face is f*cked." She added: "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."

Check out this footage from the scene , all I can say is wow

Jenner tweeted his own experience, saying: "Interesting Saturday night... Just got of the hospital with a new scar on my face.. Charges/chargers!!!"

Lavigne's rep could not be reached by Billboard.com for comment.
