Singer Michael Bublé and his wife are expecting again!

The "Haven't Met You Yet" crooner has baby number two on the way with wife Luisana Lopilato, and the pair announced the pregnancy with one of the cutest social media reveals we've seen.

The couple enlisted the help of their son, Noah, to star in a brief video clip that Buble posted to Facebook on Monday afternoon, along with the caption, "Noah has some news to tell you..."

In the short video, Lopilato is sprawled out on the floor, dressed casually in jeans, with her shirt lifted up to expose her bare tummy.

Off camera, the singer asks his son, "Who's that in there?" Noah, walking over to his mama and kneeling to put his hand to her belly, says, "Baby!" Bublé then is heard laughing behind the camera.

The clip is just eight seconds long, but sends the sweet message loud and clear!

In the past 18 hours, the post has garnered 2.6 million views, plus more than 130,000 likes and more than 3,000 shares from fans and well wishers.

Lopilato—who is herself a singer, as well as an actress and model—also shared the vid on her Instagram feed, captioning it in Spanish: "Noah tiene algo para decirles." ("Noah has something to tell you!") Her version has also racked up the likes, nearing 50,000 at last check.

Bublé's charming video is just the latest way an expecting celebrity parent has announced the big news. See stars' other fun reveals here!
