Jessica Alba didn't go "crazy" with food during her second pregnancy.

The stunning actress gave birth to daughter Haven in August and says the reason she has already regained her post-baby figure is because she was sensible while she was expecting.

She told Us Weekly: "I didn't gain as much weight with my second pregnancy, so I think that really made a big difference. I did pre-natal yoga up until the very end. I just made healthier choices. I started working out and not going too crazy, but I did what was safe and what the doctor approved."

Jessica - who also has a three-year-old daughter, Honor, with husband Cash Warren - says she's enjoying every moment of Haven as she's less nervous than when Honor was a tiny baby.

She said: "It's nice to enjoy having a newborn instead of being overwhelmed and wonder if everything is going to be okay. Now I'm like, 'Oh, she'll be fine!' They're so sweet together."
