Jessica Alba stepped out in LA Friday just two weeks after giving birth to her second daughter, Haven Garner Warren. Big sister Honor accompanied Jessica on a visit to Santa Monica's Promenade while baby Haven stayed home. The mom of two stayed active during her pregnancy, though Jessica credits her quick slim down to genetics, saying, "My grandmother was amazing — would go home in the clothes that she wore before she got pregnant with all five of her kids . . . It's definitely good genetics."
