Jessica Alba's MET Gala Baby Bump

Her second pregnancy is treating her quite well – and Jessica Alba was looking picture perfect at Monday night’s (May 2) Costume Institute Gala in New York City.

The “Machete” mama was joined by her stylish hubby, Cash Warren, as she glowed in a floorleghth Ralph Lauren Collection gown with Casadei heels at the Metropolitan Art Museum venue.

The Costume Institute Gala, one of the biggest events in the fashion calendar, was held in tribute to designer Alexander McQueen, who took his own life last February.

The fete was chaired by actress Salma Hayek and her husband Francois Henri Pinault.
