All the rumours running around rockers Avril Lavigne and hubby Deryck Whibley are not being helped by her behaviour lately! The couple refuse to announce whether they are divorcing or not, even though we keep seeing Avril partying without Deryck and always with some random guy! Last night she tried to sneak out the back door of Hollywood's Koi restaurant with another mystery guy that definitely wasn't her husband! What is Avril up to we wonder, this doesn't look good for her at all!
