Pop-punk singer Avril Lavigne and her boyfriend Brody Jenner were involved in a fight outside the Hollywood Roosevelt Hotel early this morning. Lavigne was apparently "jumped" by five people on the street, who fled into the night after roughing her up and breaking a bottle over Jenner's head. It's a curious story indeed! TMZ originally reported that Lavigne was attacked by "an unknown woman," and little details have emerged since other than the updated news that the fight was in fact some sort of brawl. But what was the cause?

Perhaps the girl in question is a Brody admirer who decided to act out the lyrics of Lavigne's 2007 hit single "Girlfriend" by attacking his lady-friend while screeching "hey hey you you hey hey!!!" Maybe the five strangers are disgruntled Sum 41 fans who theorized that the Lavigne's divorce from the punk band's frontman Deryck Whibley last year had a negative affect on the band's current output. Or maybe the group are upset about Kim Kardashian's divorce and decided to take their anger out on her step-brother's forehead.

Or it could be a group of ruffians who still can't get "Complicated" out of their heads and are still pissed about the series finale of The Hills.

Whatever the reason, Lavigne claims that her "face is fucked" and offers the following PSA to her fans via Twitter: "So not ok to be abusive to others. Violence is NEVER the answer." So, yeah,
