Even after seeing this picture, we STILL can't believe Avril Lavigne and Chad Kroeger are engaged!

Avril's rep confirmed the news yesterday, and today the lovebirds are featured on the new issue of Hello Canada. Avril flashes her massive 14-carat diamond ring on the cover of the special double issue, and the two open up about their relationship.

Back in February Avril and Chad (Chavril?) met while working on her upcoming fifth album, and Kroeger tells the mag, "I knew I was falling for her. It was incredibly powerful and something I'll never forget ... I feel like the luckiest person alive because I get to be with my best friend every day!"

The 27-year-old songstress adds, "[Chad] makes me laugh every day. He takes care of me in every way and is extremely attentive."
