Avril Lavigne and Deryck Whibley: Next Stop, Splitsville?

Rumors are once again surfacing that Avril Lavigne and Deryck Whibley’s marriage is in serious trouble.

The New York Daily News reports that the “Sk8er Boi” warbler and the Sum 41 singer are on the fast track for divorce.

A source tells the paper that Lavigne blew off steam—and her hubby—last weekend, raging on the party circuit in Southampton.

“She wanted to get away from Deryck and have a weekend to herself,” the source says, adding that she was spotted that Saturday night partying down with a complement of male admirers.

Later, Lavigne took the show to Ax Lounge, where she boogied down on the dance floor, perhaps symbolically trying to shake free from the shackles of a failed marriage.
