TORONTO - It's a Canadian coupling nobody saw coming.
People magazine reports pop-punker Avril Lavigne and Nickelback frontman Chad Kroeger are engaged after a six-month courtship that seemingly flew completely under the radar of media outlets and fans alike.
Nickelback appeared to verify the news Tuesday, posting on its website and official Twitter account, "Congrats Chad and Avril!" along with a link to the People article.
Lavigne retweeted the Nickelback note on her Twitter account and then tweeted her thanks to the multiple congratulations that came her way.
People says the romance began after the two got together in February to co-write a song for Lavigne's upcoming fifth studio album.
Kroeger, 37, has never been married before. People says the Hanna, Alta., native proposed to Lavigne with a 14-carat diamond ring on Aug. 8.
Lavigne, 27, of Napanee, Ont., filed for divorce from fellow Canuck rocker Deryck Whibley of Sum 41 in 2009.
The reported engagement was trending on Twitter on Tuesday night with many expressing their surprise at the news.
