Jessica Alba may be the co-founder of a billion-dollar business but that doesn't mean she doesn't buy her own food!

The movie star-turned-business woman grabbed some groceries at high-end market Bristol Farms on Sunday. Alba was joined by her hubby Cash Warren and their two little girls Honor, seven, and Haven, four, at the supermarket in Beverly Hills.

It looks like the fam was shopping for a special occasion -- they had a bounty of white hydrangeas and a mound of ice in their shopping carts. We have a feeling the family of four had a fun-filled BBQ at their home. Umm can we come?!

Jessica looked easy breezy in a blue dress, layered under a white cardigan. The 34-year-old kept her off-duty outfit cool with a pair of sandals. Cash opted for a white shirt and blue shorts and their two daughters looked adorbs in summery frocks.

What a sweet family!
