Rocker couple Avril Lavigne and Deryck Whibley are headed for divorce, sources tell the New York Daily News. The two, married since 2006, haven’t been photographed together since last December, and have been spotted at events and on vacations alone. Lavigne recently “wanted to get away from Deryck and have a weekend to herself” in Southampton, a source says, but she spent all her time with a bevy of guys. (More Avril Lavigne stories.)
