Chad Kroeger mocks Sum 41's Deryck Whibley for Avril Lavigne Halloween costume Get Tickets
The Sum 41 front man and his partner, Ari Cooper, go to a party in Kroeger and Lavigne costumes
The Sum 41 frontman, who was once married to the 'Complicated' singer, was joined at the party by his model partner Ari Cooper, who went dressed as Kroeger.
After seeing a photo of the pair at the party, Kroeger went on his Twitter and suggested that he and Lavigne were considering going out for Halloween dressed up as Sum 41, but added that the band weren't famous enough for them to bother with the effort.
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— Nickelback (@Nickelback) October 28, 2012
Avril Lavigne was married to Deryck Whibley for three years, but the couple split up in 2009. She went on to date American TV star Brody Jenner, who is Kim Kardashian's stepbrother, but they broke up at the beginning of 2012.
Chad Kroeger, who is 10 years Lavigne's senior, has previously said that he doesn't care about "the world's opinion" of their engagement, adding that he and the singer were "both very happy".
