While this is pretty funny, it almost makes Avril Lavigne’s ex-hubby Deryck Whibley look a little bitter, no? Avril and the Sum 41 frontman broke up a few years back, and both have since moved on. Avril is now engaged to Nickelback singer Chad Kroeger, while Deryck is dating model Ari Parker. But for this Halloween, Deryck and Ari pulled a little switcheroo and decided to dress as Avril and Chad! The costumes were pretty good, but even better was Chad’s zinger in response on Twitter! He got at Deryck good! Check it out in the gallery.
