Deryck Whibley dressed as Avril Lavigne to stop her from marrying Chad Kroeger

I think most of us were amused when Avril Lavigne’s ex, Deryck Whibley, and his girlfriend, Ari Cooper, dressed up as Avril and Chad Kroeger for Halloween. My take on it at the time was that Deryck had tried to go covert, but someone had done the inevitable and posted a photo on Twitter, which is something that Deryck should have expected. It turns out that I was wrong — at least, according to a story in this week’s Star — and Deryck really wanted Avril to set her eyes on his hilariously ridiculous costume because he thought it was a great way to break up Avril and Chad, thereby stopping their impending nuptuals. However, the plan has reportedly backfired (of course), and Avril is furious with Deryck. How exactly did he not see this coming?

Friends and fans were shocked when Avril Lavigne announced her engagement to Nickelback singer Chad Kroeger — and her ex-husband, Deryck Whibley, is determined to break them up! “Deryck is still good friends with Avril and is very concerned,” explains a pal. “He’s only heard negative things about Chad, like he’s a ladies’ man and has a tember. Deryck is convinced he’ll cheat on her or treat her like crap.”

But Avril, 28, made it clear to the Sum 41 frontman, whom she split from in 2009 after three years of marriage, that nothing he can say — or wear — will stop her. In an attempt to make a public statement against Avril’s engagement, Deryck, 32, dressed up as his punky former wife for Halloween, with his girlfriend, Ari Cooper, masquerading as Chad. But the plan backfired. “Hey Deryck loved the costumes! we were going to dres sup as you guys this year but all the parties had celebrity themes haha! — CK” tweeted Chad, 38, after seeing the pictures. Sources reveal that Avril wasn’t amused. “The stunt only made Avril resent Deryck, which was the last thing he wanted. He’s just hoping that she really thinks things through before rushing down the aisle.” Why’d he have to go and make things so complicated?

Meanwhile, Chad has admitted during an interview with Men’s Health (wtf?) that Avril really isn’t that familiar with Nickelback’s music (can you blame her?). In fact, Chad says that she probably wouldn’t recognize one of his “naughty” songs if it came on the radio, but he insists that “She’d be like, ‘Who’s this? This is good. I like it.” Whatever, dude. This revelation only confirms to me that Avril isn’t so much into Chad as she is in the tacky-ass, 14-carat diamond ring that he gave her. Sounds like this marriage will be a real winner.

This photo of Deryck and his girlfriend, Ari Cooper, was taken at the launch of Avril’s horrific Abbey Dawn clothing line on March 13. So I guess maybe they really still are friends, but it doesn’t sound like that will be the case for long.
