The video shows what appears to be an ultrasound of a fetus with the words “Mini Buble !!!” attached to the image.
A written statement that also is part of the 21-second video says, “We’re having a baby Buble!!!”
Buble, 37, is a three-time Grammy Award winner known for such songs as “Haven’t Met You Yet,” “Home,” and “Save the Last Dance for Me.”
He and Lopilato, 25, were married in 2011.
