Michael Bublé and his wife, Luisana Lopilato, are almost ready to be a family of six! The 46-year-old singer brought 34-year-old Lopilato to the Billboard Music Awards on Sunday, marking the couple's first red carpet appearance together since they announced Lopilato's fourth pregnancy back in February. «This is the most fun I’ve ever had on a red carpet,» Bublé told ET's Cassie DiLaura, before joking that they wouldn't even have to take maternity photos after attending the event. «Paparazzi took a bunch of us and now I'll just download them off of Google and put them up in my house.» Lopilato shared she's been «feeling so good» throughout her pregnancy and expressed that she was «so happy that we’re here together.»The couple has been married since 2011 and they have three other children, sons Noah and Elias, and daughter Vida. But they still haven’t decided on a name for baby No.
