Canadian singer-actress Avril Lavigne has fuelled rumours she is set to split from husband Deryck Whibley after a series of solo nightouts in New York.

Lavigne and Whibley married in 2006 but were the target of speculation just two years later after a US tabloid reported they were on the verge of divorce.

Ok reports, Whibley denied the rumours at the time, insisting he had been spending a lot of time away from his wife while he toured Asia with his band, Sum 41, but the "Complicated" hitmaker Lavigne has attracted speculation once again after partying in the company of male admirers in Southampton, New York last weekend, with insiders saying that the stars' divorce is imminent.

"She wanted to get away from Deryck and have a weekend to herself," said a source.
