Jessica Alba indulged in some retail therapy at the weekend and took baby daughter Honor Marie along for her first shopping trip.

The pair looked adorable together as they waited for daddy to pack up the groceries at the supermarket.

The new parents – who have just got back from a family trip to Mexico – later spent the day at a friend’s birthday party in San Fernando Valley.

And, as to be expected, Jessica is skinnier than ever after shedding her post pregnancy weight faster that you can say baby.

“She worked out an hour a day, five or six days a week, and stayed on a strict diet of about 1700 calories a day, losing 600 calories because of exercise,” Jess' trainer told People.

And three months later, the Sin City star is very much the yummy mummy.
