We had no idea they were even dating, but Nickelback frontman Chad Kroeger proposed to Avril Lavigne on August 8 and she said yes.
The pair have apparently been together for six months, but kept is so quiet that few knew they were an item. The relationship started when Kroeger was recruited to co-write a song on Lavigne's new album.
"A romantic relationship blossomed as they spent time writing together," one of her friends told People magazine. "He makes her so happy. Both of their families could not be more excited."
Perhaps there was a message in Nickelback's latest single, "Trying Not To Love You". A video was posted only two days ago.
Kroeger has never been married, but Lavigne tied the knot with Sum 41 frontman Deryck Whibley in 2006. Their marriage ended three years later.
In other recent Nickelback news, a fan fell down a 40-foot gorge while trying to sneak into one of their shows. Now that's dedicated.
Congratulations to both Chad and Avril on their engagement!
