Michael, who is expecting a son with Luisana, was due to be interviewed on America's Today show today (9 August), but has recorded a short message explaining why he won't be appearing.
The clip starts with Michael playing a child's white piano. He then says: "Fortunately, and unfortunately, there is something really big that's really close in my life and it's right here."
The Canadian singer then reaches out and touches Luisana's bump. Although the camera doesn't show his wife's face, viewers get a great glimpse of her pregnant tummy!
Michael continues: "So, I won't be there but I'll see you guys really soon on the road and I'll be bringing somebody extra with me." Aww!
Michael and Argentinian model Luisana, who married in 2011, announced in January that they were expecting a baby with a cute 'mini Bublé' video message.
In March, Michael then revealed that Luisana was expecting a boy, adding: "We're thrilled!"
One thing's for sure, that little lad is going to sleep the whole night through if his dad puts him to bed with a lullaby!
