Luisana Lopilato Stuns In Pre-Baby Photo Shoot: Michael Bublé's Wife Models Swimsuits For Ultimo (PHOTOS)


Michael Bublé is one of the luckiest men in the world and not just because he's an internationally successful singer.

The Canadian's wife, Luisana Lopilato, who is pregnant with their first child, is a total knockout and we've got the photos to prove it.

Before the 26-year-old actress announced her pregnancy in January, Luisana posed for UK lingerie company Ultimo, in a series of sexy swimsuits which didn't reveal a hint of a baby bump.

The Argentinian beauty showcased her killer curves in a black and white striped bikini, a black halter swimsuit and a Baywatch-esque red bikini.

We can't decide whether the blond bombshell with the killer smile is more beautiful pre-pregnancy or with a blooming baby bump.

Lopilato, who hails from Buenos Aires, showed off her growing tummy in a stunning red lace gown with a slit up to there at the 2013 Juno Awards. Hubby Michael Bublé, who hosted the event, stood beside his beautiful wife looking happy and proud. Aw, they're so cute!

The adorable couple, who met on the set of Bublé's music video "Haven't Met You Yet", got engaged in 2009 and married in Argentina in 2011. They confirmed they were expecting a baby boy in March.

We just hope their young tot will get mom's looks!
