A photograph showing the injuries sustained by pop-rocker Avril Lavigne in a vicious attack over the weekend has surfaced online. 

The 'What The Hell' hitmaker was assaulted by 5 people in Los Angeles on Sunday, November 6 and took to social networking site Twitter to tell her fans about the dramatic ordeal.

She explained to her followers that she suffered a "black eye, bloody nose, hair ripped out, scratches, bruises and cuts" and stressed that "violence is NEVER the answer". 

The picture, which was originally posted on PerezHilton.com, shows Lavigne with a deep cut above her eye and scratches covering both her cheek and face. Following the attack, her boyfriend Brody Jenner tweeted: 

"Interesting Saturday night... Just got of the hospital with a new scar on my face.. Charges/chargers!!!"
