Derek Whibley, Sum 41 frontman, dressed up as his ex-wife Avril Lavigne while his girlfriend dressed up as Lavigne’s current husband, Nickelback’s Chad Kroeger.
Upon seeing this photo on Twitter, Kroeger Tweeted, “Hey Deryck loved the costumes! we were going to dress up as you guys this year but all the parties had celebrity themes haha! -CK”
Good one! Lavigne has yet to weigh in.
