Michael Buble`s wife expecting a boy

New York: Singer Michael Buble and his wife are expecting a baby boy, ultrasound scans have revealed.

The 37-year-old `Haven`t Met You Yet` hitmaker and model Luisana Lopilato, who married in March 2011 after over two years together, were delighted to be told that they will be welcoming a son in August, New York Post.

"We are so excited. We have just come from the hospital, and the sonogram was pretty clear, it`s a boy! We are thrilled," Buble said.

The couple are now thinking of a list of names for their impending new arrival, but Buble insists the baby won`t be named after the new pope, Pope Francis I - who, like Luisana, hails from Argentina.

"She said, `It is a sign!` But there`s no way we are going to call him Frank, even if it did work well for Frank Sinatra."
