The couple met while working on Lavigne's forthcoming fifth album in February, and Kroeger popped the question August 8. "I knew I was falling for her," Kroeger told Hello! Canada of their intense studio sessions. "It was incredibly powerful and something I'll never forget."

According to once-wed Lavigne, Kroeger "makes me laugh every day. He takes care of me in every way and is extremely attentive."
