Michael Bublé is expecting his first baby, but who is the babe he's married to?

Luisana Lopilato, a 25-year-old actress and model from Argentina, married the "Hold On" singer two years ago -- and though she may be unfamiliar to North Americans, she is a big star in her home country.

The Buenos Aires beauty, who made her onscreen debut at age 8, rose to fame in 1999 as the star of a local children's musical series, "Chiquitas," for which she also recorded four soundtracks.

As a teenager, in 2002 Lopilato formed the pop band Erreway with her co-stars on the TV series "Rebelde Way." Five years and millions of records sold later, she left the group to pursue a solo career. Lopilato was later named "The Face of the Year" by Gente magazine (Argentina's version of People) after appearing in a number of plays and TV series like the Argentinian version of "Married ... With Children" ("Casados Con Hijos"), not to mention becoming the face of Promesse lingerie. And in 2009, Spanish FHM ranked her as No. 86 in its annual list of 100 Sexiest Women in the World.

Bublé met Lopilato in November 2008, months after his high-profile breakup with British actress Emily Blunt, at a party in Buenos Aires thrown by the 37-year-old Canadian crooner's record company. The couple got engaged a year later and wed in March 2011 in Argentina.

"Haven't Met You Yet," the first single from Bublé's fourth album "Crazy Love," was released in August 2009, and the crooner dedicated it to his new fiancée. She appeared in the music video as well.

On Thursday, Lopilato and Bublé announced yesterday on her website that they are expecting their first child.

"Mike and I have big news for you," she wrote with a link to a YouTube video which showed a sonogram scan and the message, "We're having a baby Bublé!"

But perhaps the bigger surprise is that the tot already has a potential "stepdad." One Direction member Niall Horan, who has in the past called Bublé his "man crush," was named second baby daddy after he congratulated the duo on their upcoming production.

"@NiallOfficial I wish that you could have been the father!!" Lopilato tweeted in response. "Hahah I went the 'wrong direction' @michaelbuble says you can be the stepdad."
