Avril Lavigne and Deryck Whibley on the Verge of Splitting

Bad news comes from Avril Lavigne as rumor has it, her marriage to musician hubby Deryck Whibley is on the rocks. The National Enquirer broke the report that the celebrity couple, who has been married for more than two years, is on the verge of splitting.

The magazine cited a source as informing Avril and Deryck have been growing apart since she started her world tour earlier this year. "Deryck isn't motivated in his own career, so he's been drinking and partying," the source revealed.

Adding fuel to the rumors of possible separation, Deryck reportedly has been spotted attending an event at a Los Angeles nightclub recently, during when he was seen huddling at a private table and holding the hand of an unknown woman. A spokesperson for Avril and Deryck had not yet returned requests for comment. Neither of the singers also has comment on the extent of their relationship.

Avril and Deryck, the guitarist and lead vocalist of band Sum 41, began dating in the beginning of 2004. The couple then got engaged in June the following year and tied the knot in a traditional Catholic wedding ceremony on July 15, 2006 at a private estate in the California coastal city of Montecito, located about 87 miles northwest of Los Angeles.
