Baby Buble has arrived!  Michael Buble and his wife Luisana announced the birth of their first child, a boy named Noah, on Tuesday.

Posting a photo of mom, baby and himself in the hospital on Instagram, Michael wrote, "Overjoyed and filled with gratitude at the arrival of our son Noah Buble. Born this morning, August 27th at 2:26 am in Vancouver, Canada."

Michael has been talking non-stop about his excitement over the impending arrival ever since he and Luisana announced they were expecting back in January.  

"I don't know what to expect, because obviously, I've never expected before," Michael told ET Canada.  "I'm just really, actually enjoying [the anticipation].  To be honest, neither of us are anxious, we're just excited.  We can't wait to know what it's like; we can't wait to meet this little guy."

Next up for Michael: a major U.S. tour, which kicks off September 7 in Chicago.
