Avril Lavigne Files for Divorce

Avril Lavigne has filed for divorce from Deryck Whibley.

She cites "irreconcilable differences."

According to the docs, Avril says they separated on Sept. 4th and were married 3 years and 1 month.

Avril is not asking for spousal support -- probably because she's the breadwinner -- and she also checked the box in the docs saying she doesn't want to have to pay Deryck any money.
