Michael Buble, Luisana Lopilato expecting second child

Michael Bublé and wife Luisana Lopilato are expecting their second child.

The 39-year-old Canadian singer and 28-year-old Argentine actress announced the news with the help of son Noah in a Facebook post Monday.

Bublé uploaded a video of Lopilato lying on the ground and prompted Noah to reveal his mom has a "baby" in her belly. Much to fans' delight, Britney Spears hit "Oops...I Did It Again" was playing in the background.

Bublé and Lopilato met on the set of the singer's music video for "Haven't Met You Yet" in 2009, and married in Buenos Aires, Argentina, in March 2011. The couple welcomed Noah in August 2013.
