Looking bright and beautiful in a multicolored scarf, Jessica Alba celebrated her 31st birthday with a low-key dinner at trendy Cuban restaurant La Descarga in Hollywood, on Thursday evening.

The sexy mom of two was accompanied by hubby Cash Warren and a few non-celeb friends, and the Fantastic Four star shared a pic of her big birthday cake, via Facebook!

Alba's actual birthday is April 28, and she celebrated the milestone by painfully getting her ears pierced again. Ouch! The Birthday Girl shared via Twitter, "Getting my second pierce re-pierced!"
