Jessica Alba showed off her stunning post baby body at the 2008 ALMAAwards just two months after giving birth.  The actress has already lost25 lbs of the baby weight and her trainer tells People howshe did it:

“Jessica went from a size 8 to a size 4 pretty quickly,” says Alba's longtimetrainer Ramona Braganza. The actress  has been opting for a low-fat,low-carb diet as part of Braganza's 321 Baby Bulge Be Gone plan.

She has been sweating, too: With an elliptical machine and treadmill at home, Alba,27, has resumed her routine of core exercises, cardio and circuit training.

"The baby always comes first, but Jessica definitely set goals for herself,” saysBraganza, who now trains Alba six days a week.

And having a workout buddy helped. “She loves working out with a girlfriend,” saysBraganza, whose client, actress Jamie King, frequently trains with Alba.

Says Braganza: “Jessica has made amazing progress in a very short time.”

She sure does look healthy and happy. If you want more details you can read the completestory in the newest issue of People on newsstands tomorrow!
