Jennifer Hudson has been working overtime to shed her post-baby weight and word on the street is that she’s lost over 56 lbs to slim down for her upcoming role as Winnie Mandela. The photo on the right was taken back in October while the one on the left was taken a just a few weeks ago at a pre-grammy gala.

You may have also noticed Jenn’s slimmer physique during her the 2010 Grammy Awards. Well, the 28 year-old new mom who welcomed her first child, in August last year admits it hasn’t been easy. Jenn says she dropped the baby weight by being sensible, and she would advise every other new mom to do the same instead of crash dieting.

?I don?t really diet as such,? she says. ?I actually get up and work hard every day. I make sure I eat right and just make sure I stay focused. It is about being consistent and sticking with it.

Jenn’s been loving every minute of motherhood and says that her son, David Jr. is “the most beautiful person in my life”. When pressed about her future plans, Jenn admits that a lil girl (or two) would make their happy home complete:

?I?d like to have at least one more, a little girl. I want a girl and then maybe another one. You know, one baby at a time.?

Hudson has been working with celebrity trainer Harvey Pasternak (who is credited with getting Jessica Simpson in her Daisy Dukes).

You betta work!
