Michael Buble is opening up about his three-year relationship with Emily Blunt.

Although the 40-year-old Canadian crooner and the 32-year-old British actress split in 2008 amid rumors of infidelity on Buble's part, he tells ET Canada in a new interview that cheating was not the reason behind their breakup.

"It didn't end because of cheating," Buble says. "It ended because we weren't right for each other, and we are now exactly where we're supposed to be in our lives."

Both Buble and Blunt are now happily married to their respective spouses. The "Everything" singer has been married to Argentine actress Luisana Lopilato since March 2011, and Blunt has been married to The Office star John Krasinski since July 2010. Buble says he's forever grateful for the time he spent with the Into the Woods star.

"Emily is a beautiful and loving person, and I'm grateful for the time I had with her, for the relationship," Buble says. "Without it, I wouldn't have had a chance to fall in love with myself enough to be with a woman like my wife."

Blunt herself recently addressed the cheating rumors, when she appeared on Howard Stern's SiriusXM show last month.

"I don't know, it's complicated," Blunt said, exclaiming: "I'm going red!"

"I never want to talk about it," she explained, adding that the two "had a good time" and that she still loves his family. "I can't do it."

These days, both Buble and Blunt are proud parents. Blunt is mom to 1-year-old Hazel, and Buble has a 2-year-old son named Noah, with another child on the way.

And he doesn't rule out the possibility of more kids in the future!

"You know, Noah's two and I already miss him when he was a baby," Buble shares. "We love that part so much that how can we not want to have that again? And again, and again... I'm saying that now, let's see what I say after two."
