Jessica Alba santa monica dress soda hand bag sunglasses

Jessica Alba was snapped heading to a meeting in Santa Monica on Thursday, and the 31-year-old starlet wasn't in the best mood, but she still looked gorgeous!

Jess is going to begin shooting on Sin City 2 very shortly (she's already done some prep work) but in addition to running her company and taking care of her darling daughters, she's also getting involved in politics.

The Obama campaign just launched its “For All” campaign, which encourages Americans to take pictures of themselves with their hands over their hearts and a note explaining why they support the president.

Alba wrote in a letter, “Growing up, my classmates and I started every day with a ritual: We’d stand up, put our right hand over our hearts, and say the Pledge of Allegiance,” explains Alba. “To me, that gesture was a promise. A promise to be involved and engaged in this country’s future. A promise to work for liberty and justice — and for affordable education, health care, and equality — for all.”

She added, “Make sure you’re ready to vote this fall. Putting your hand over your heart is making a promise. Casting your ballot is keeping it.”
