Sarah Jessica Parker has confessed she is desperate to put on weight and insists she is always trying to plump up. The Sex in the City star reveals, “I’m an eater – and I love junk food. I’m going to wake up one day and I’ll be triple my size and I’ll say, ‘Ha, the joke’s on me!'” Sarah Jessica – who has a three-year-old son – also criticised celebrity mums who crash diet after giving birth. She says, “There’s all this emphasis on losing weight after a baby. Look at Posh Spice! It’s not easy to take off weight after giving birth. Do what’s good for you and your child!”
