Avril Lavigne filed for divorce from Sum 41 singer Deryck Whibley on Friday in Los Angeles. The couple were married in July 2006 and have no children together. Avril Lavigne cited ”irreconcilable differences.” The 25 year old punk pop singer burst to fame with her 2002  CD “Let’s Go.” Avril Lavigne is asking a ruling to block Deryck Whibley from receiving spousal support. Court records show Deryck Whibley was granted a request to add Lavigne’s last name to his name in December 2007.
