"It is with heavy heart that Chad and I announce our separation today," she wrote. "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."
"I believe that I will come out of this healthier and stronger than I was before," Lavigne said. "I’ve gained a lot of perspective on my life."
This is Lavigne's second marriage. She was also wed to Deryck Whibley from 2006 to 2009.
