A big congratulations to Michael Buble and his wife! They are expecting their second child and made the announcement in an adorable way.

On Monday, Buble posted a video to his Instagram page which shows his 1 1/2-year-old son, Noah, pointing to his mother's belly and says "baby" when his Dad asks him "who's that in there?" You also hear Britney Spears' "Oops, I Did It Again" playing in the background. Hmm.. I wonder if that was a coincidence LOL.

Buble and his wife have been married since 2011. And if you know anything about Buble than you know he's a humble, down-to-earth guy with a great sense of humor. Plus he's handsome and can sing like Frank Sinatra. He's pretty much perfect. Mrs. Buble is one lucky lady!

You can see the video here on Michael's Facebook page.
