Nickelback’s Chad Kroeger has mocked Sum 41′s Deryck Whibley for dressing up as his future wife, Avril Lavigne, for a weekend Halloween party.
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.
