　　"Avril Lavigne & Deryck Whibley's Close (and Friendly!) Encounter in L.A.".

　　Avril Lavigne had some special support at a party to launch her Abbey Dawn accessories line in L.A.: her ex-husband, Deryck Whibley!

　　The Sum41 rocker came out to the JustFabulous party at the Viper Room, and even shared a hug with Lavigne, who reportedly split from her boyfriend Brody Jenner in January. Whibley also posed for pictures at the event and congratulated Lavigne on her hard work.
