What is going on between Avril Lavigne and former husband Deryck Whibley? The couple decided to get divorce last October, and each of them went on with his life.

Until Thursday night. The two of them have been photographed in the back of a limo. According to TMZ.com, that night, the couple left 'Alice in Wonderland' afterparty and carpooled to a London hotel.

Just when we were thinking that Avril was sharing a romance with 'The Hills' star Brody Jenner! Life is just so complicated!
