The actress wants the world to know her secret to losing weight after having a baby, and Alba insists that it has nothing to do with diet or exercise, reports People.
The star explained, "I wore a girdle. Eight weeks after my girlfriend had her baby, you could see her six-pack. She told me to put an elastic band around my waist – any kind of band or girdle works."
Alba did, however, admit that she didn’t lose the weight as fast as her friend.
