LOS ANGELES – Court records show Avril Lavigne has filed for divorce from her musician husband after three years of marriage.

Lavigne filed for divorce from Sum 41 singer Deryck Jason Whibley on Friday in Los Angeles.

The couple were married in July 2006 and have no children together. Lavigne cited "irreconcilable differences."

The 25-year-old punk-pop singer burst to fame with her 2002 debut album "Let's Go."

Lavigne is asking a ruling to block Whibley from receiving spousal support.

Court records show Whibley was granted a request to add Lavigne's last name to his name in December 2007.
