It’s Jessica Alba’s birthday today, and as seen in the pic above she’s already been celebrating, with cake and all. Jessica is one celebrity that loves twitter and the now famous instagram. All her travels and family fun is up for the world to see, and I for one think it’s so cute to see her and her family together. Here are some of my favorite Instagram pics from her twitter account (@jessicaalba), you have to follow her, she has some of the best adventures!
