Canadian crooner Michael Buble's split from girlfriend Emily Blunt has left his family devastated - because they loved the actress.

The singer's publicist, Liz Rosenberg, confirmed the couple had ended a three year romance over the weekend.

But the break-up may have hit Buble's mother, Amber, the hardest.

In a recent interview, she said, "If he doesn't marry her, I might kill him."

And even though Buble and Blunt have split, Mama Buble still hopes to call The Devil Wears Prada star a member of her family.

Speaking of a potential split back in May, Amber adds, "We'd find someone in the family to marry her because we're not letting her go - ever."
