She has a killer body, but Jessica Alba insists she has her fair share of problem areas. I have cellulite and stretch marks--and I have a muffin top, she tells Women's Health UK! The mom of two blames it on her lack of focus. I have a brutally short attention span, she added. It means I'm useless at work outs. I get so bored. Muffin top? You do a pretty good job of covering it, Jess!
