PHOTOS: Evidence That Jessica Alba Can Smile in Public

For as often as Jessica Alba allows herself to be photographed by hitting up restaurants and stores notorious for being paparazzi hangouts, the actress can rarely be bothered to crack a smile. But the Valentine's Day star seemed to be in better spirits than usual on Tuesday as she headed home after visiting a studio in Santa Monica — she even briefly showed off that grin she normally reserves for red carpet appearances. Note to Jess: You're wealthy, famous, a good mom, and beautiful. Don't be so glum all the time!
