Pop rocker Avril Lavigne was left battered and bruised after being "attacked by 5 people" in Los Angeles over the weekend. 

Writing to her 2.7 million followers on social networking site Twitter last night, November 6, the 'What The Hell' star explained that she was left with mulitple injuries after the unprovoked assault and is disgusted by the incident:

"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."

Talking specifically about the repercussions of the fight, Lavigne explained that she now has 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," she continued. Watch her latest music video for 'Wish You Were Here' below:
