The couple is already parents to sons Noah, five, and Elias, two, as well as four-month-old daughter Vida, and while the singer would love to add to his brood he insists that decision rests entirely on Luisana's shoulders.
"I love that you have enough respect for me to actually pretend to believe that I get to have any choice in the matter," he told Britain's Hello! magazine. "That's my wife's body and she's the boss of everything, so she'll decide that. I really have zero say. I hope to have the opportunity to try."
Michael and the Argentine actress have been married since March, 2011 and the Canadian crooner added that he feels "blessed to have three" kids.
He recently released his 10th studio album, titled "Love" - his first record after a two-year hiatus, in which he took time out of the limelight to care for Noah as he battled liver cancer. Noah has since gone on to make a full recovery and Michael is gearing up to go back on tour, commencing on February 13, 2019 in Tampa, Florida.
"I get to reconnect with all those beautiful spirits, souls all over the world, and get to do what I love," he smiled. "My wife is going to back to making her movies and I get to juggle this beautiful, personal, crazy life with everything - with kids and school."
