Avril Lavigne fell for Chad Kroeger's sense of humour.
The 27-year-old singer recently announced her engagement to the Nickelback frontman and says one of the things that attracted her to him was how much he made her laugh.
She said: "He makes me laugh every day. He takes care of me in every way and is extremely attentive."
Chad says he fell for Avril while they were in the studio together working on her fifth album.
He told Hello! Canada: "I knew I was falling for her. It was incredibly powerful and something I'll never forget."
Sources close to Avril and Chad - who have been dating for around six months - say they are a perfect match because they have the same beliefs.
One told PEOPLE: "They have the same values and really understand each other. They complement each other and are so happy.
"They haven't set a date yet. They're really enjoying this moment."
The marriage will be the second for Avril, who wed Sum 41 singer Deryck Whibley in July 2006, splitting three years later.
Following her separation from the rocker, she went on to date reality TV star Brody Jenner for two years until January 2012.Chad has never previously been married.
