Luisana Lopilato is making headlines thanks to her sizzling pre-pregnancy swimwear photo shoot for Ultimo, but Micheal Bublé's wife wasn't always a style savvy goddess.

The 26-year-old Argentine got her start in television, appearing in shows "Mi familia es un dibujo" and "Chiquititas" in the 1990s before landing a recording contract with Universal Music Group in 2007 (watch her music video "Te extraño - Atracción x4 en Dream Beach").

Apart from a number of films, the avid Twitter user is also a model, having been the face of underwear brand Promesse and of course, her deal with UK lingerie company Ultimo.

Luisana, who barely spoke English when she and Bublé got married in 2011 (check out their beautiful wedding photos), is expecting a baby boy with the Canadian crooner.

Pregnant celebrities wished they looked as good as Luisana. The yummy mummy-to-be recently wowed in a red lace dress with a slit up to there at the 2013 Juno Awards and showed off her blooming baby bump in cut-off shorts and a simple white tee in March.

But Luisana didn't always have such impeccable style. Click through the photos below to see her style evolution.
