Jessica Alba has a "muffin top" because she is "useless" in the gym.
The 'Machete' actress has a reputation for keeping her lean figure despite having children Honor Warren, five, and Haven Warren, two, but insists she still has a number of imperfections, including her tummy bulging over her waist of her trousers, known as a "muffin top".
Jessica told Women's Health UK: "I have cellulite and stretch marks -and I have a muffin top! I have a brutally short attention span. It means I'm useless at work out. I get so bored."
The 32-year-old's lack of workouts are outweighed by the fact she has restricted herself to a healthy diet from a young age.
She continued: "I started cooking for myself at 12 because a lot of food my family ate was processed. I wanted fresh. I eliminated microwave foods, things with too much salt, and tried to eat more natural food, things that were cooked in a kitchen as opposed to a factory."
Jessica - who is married to film producer Cash Warren - has collected all her healthy recipes in a new book, 'The Honest Life: Living Naturally and True To You'.
The star previously claimed her book was "more grounded" than vegetarian actress Gwyneth Paltrow's latest cookbook, 'It's All Good'.
She told The New York Daily News newspaper: "Gwyneth Paltrow probably lives a very similar lifestyle, but I didn't grow up with a bunch of money, so my tips are much more grounded: re-purposing things and making things at home."
