Avril Lavigne has sparked rumours of a reconciliation with husband Deryck Whibley after they were photographed leaving a party in London together just four months after the singer filed for divorce.

Lavigne split from the Sum 41 rocker late last year after three years of marriage, citing "irreconcilable differences".

She has since been linked to a string of new men including The Hills star Brody Jenner and actor Wilmer Valderrama.

But Lavigne is now rumoured to have revived her relationship with Whibley after the former couple was snapped sharing a car together following the Alice in Wonderland premiere in London on Thursday night.
