Washington, Nov 19 New mum Alessandra Ambrosio has revealed that she gave up chocolate in order to win back her pre-pregnancy figure.

The supermodel, who gave birth in August (08), was back on the catwalk for the Victoria's Secret Fashion Show in Miami, Florida at the weekend (15Nov08), where she disclosed all her weight loss secrets.

"(I was) just working out, there's no magic, close your mouth. Basically don't eat any chocolate or sweets... Nothing that's kind of unhealthy. Lots of healthy food, working out a lot, lots of cardio," Contactmusic quoted Ambrosio, as telling HollyScoop.com.

Ambrosio also confirmed that she's set to wed her baby's father, California businessman Jamie Mazur, who she has been dating since 2005.

"Yes, marriage is in my plans. I'm engaged now. (But) right now I'm just concentrating on work and hanging out with my baby," she added. (ANI)
