Here's a unique idea for a Halloween costume: go as your famous ex-wife. That's what Sum 41 frontman Deryck Whibley -- Avril Lavigne 's former husband -- apparently did this weekend, and Lavigne's current love was not impressed.
According to Buzzfeed.com, Whibley and his current girlfriend, Ari Cooper , poked fun at both Avril and her new fiance, Nickelback 's Chad Kroeger , by cooking up a cross-dressing couple costume. While Whibley sported a hoodie and a blonde wig with Avril's familiar multi-colored tips, Cooper wore a blonde wig, facial hair and a Jack Daniels tee, and carried a red Solo cup with "Chad" written on it.
When the real Kroeger saw the pictures, he wrote on Twitter , "Hey Deryck loved the costumes! we were going to dress up as you guys this year but all the parties had celebrity themes haha!"
Then, to soften the diss, he added , "You owe us a couples bowling grudge match...see you when I get back from Russia!"
