Is this the most cringeworthy celeb couple of all time? We compare the Canadian duo to other icky couples from the world of showbiz.

After just six months of dating, Avril Lavigne announced she was engaged to Nickelback's front man Chad Kroeger. While we couldn't be happier for the couple, the are some out there who might think their surprise union is a little bit, well, icky. Sure, he may be 10 (but looks 20) years older than the Sk8er girl, but they have plenty in common. They're both Canadian, they were both fixtures of the best-forgotten commercialized pop-punk/grunge revival of the early 2000s, they're still peddling wildly unfashionable music and, erm, that's it.

The engagement comes as a surprise as many still thought she was dating The Hills star Brody Jenner. Avril was previously married to fellow early 2000s pop-punk star and Sum 41 super-hunk Deryk Whibley.

The pair apparently got together while working on a track for Avril's new album and have been together ever since. They've already sold their to story to Hello! magazine, and Chad has given Avril a 14 carat engagement ring.
