Lavigne announced on Instagram earlier this month that she and her husband, Chad Kroeger, are ending their marriage after two years. She said that she and her separated husband will stay friends and that she's thankful to everyone who's been supportive.

 It is with heavy heart that Chad and I announce our separation today. Through not only the marriage, but the music as well, we've created many unforgettable moments. We are still, and forever will be, the best of friends, and will always care deeply for each other. To all our family, friends and fans, thank you sincerely for the support.

In a previous post from E! News, an insider gave the impression that the reason for the split was simply due to the fact that it wasn't meant to be.

"At the end of the day, they just didn't see eye to eye on a lot of things...their friends and their circles never really mixed," the source said. "They originally got together to make an album and that's where the spark between them originated. But it just slowly died out."
