Didn’t those lyrics “I'll be at the studio, singing the song we wrote about a girl you used to know” always make you think Avril Lavigne’s “Sk8er Boi” wasn’t over his ex? Deryck Whibley’s girlfriend must be wondering if her guy isn’t still a bit hung up on his former wife, as well. The Sum 41 singer and his GF, model Ari Cooper, dressed as Avril and her fiancé, Nickelback's Chad Kroeger, over the weekend for Halloween. 

While Deryck got dolled up in a wig, eyeliner, and hoodie to impersonate his ex-wife (the couple divorced in 2009 after two years of marriage), Ari sported some facial hair and flowing locks to play the part of Chad. (The fact that “Chad” was written on her party cup also helped.)

Even if it did make us wonder about the nature of Deryck’s feelings for his ex, the costumes were still pretty hilarious. Yet not everyone was so amused. “Hey Deryck loved the costumes! we were going to dress up as you guys this year but all the parties had celebrity themes haha!” Chad tweeted from Nickelback’s Twitter account on Sunday. 

Looks like Deryck is still waiting for this world to stop hating.
