Looks like Avril Lavigne may not be getting "My Happy Ending" after all: Divorce rumors just won't stop for the singer and her husband Deryck Whibley.
New reports have surfaced that the couple, who have been married three years, have split. However, no divorce papers have surfaced and reps have not returned calls for comment.
Still, the couple have been living separate lives for some time. Last month, Lavigne, 24, and Whibley, 29, emerged together at a Beverly Hills supermarket. Despite having spent several days apart – she in New York and Texas and he in L.A. – they didn't seem thrilled to be reunited, according to an observer. "She seemed distant," the eyewitness told PEOPLE at the time.
Before their appearance together, speculation about trouble between them had been bubbling for months, fueled by public fighting, nights spent partying without each other – and Lavigne's close friendship with Brandon Davis.
"She and Brandon Davis have a good time together," a source told PEOPLE of Lavigne last month.
Whibley and Lavigne, who are both from Canada, tied the knot in July 2006 at a private estate in Montecito, Calif.
