Avril Lavigne & Deryck Whibley: Reunited in 'Wonderland'?

Are Avril Lavigne and Deryck Whibley giving love a second shot?

The 25-year-old Canadian rocker and her ex-husband were spotted at the Alice In Wonderland premiere after party together in London just before 2 a.m. Friday (February 25). Avril and Deryck left together in a waiting car but kept their distance once inside.

Deryck and Avril announced their separation in September of 2009 – “I am grateful for our time together, and I am grateful and blessed for our remaining friendship,” she wrote on her MySpace blog after the announcement.

Avril‘s rep tells ET Canada that Avril and Deryck are just friends.
