Singer Michael Bublé (pictured) and his wife, Luisana, are expecting a baby boy, he exclusively told us. The overjoyed star said, “We are so excited. We have just come from the hospital, and the sonogram was pretty clear, it’s a boy! We are thrilled.” He said he and his Argentine wife, who’s due to give birth to their first son in August, saw doctors after learning the new pope is from her country. Bublé said, “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.”
