Lindsay Lohan never sleeps!

Lindsay Lohan has hit back at claims she is partying too hard - insisting she and her mom will decide if she needs to calm down. Lindsay has earned a reputation as one of Hollywood's biggest party girls during her short career. She was even photographed wearing no underwear during a recent night out in London (classy at least keep your legs closed).

Lindsay, insists she would slow down if her mother Dina told her to. I doubt Dina will say anything she is usually having a drink and dancing right next to her. She revealed to Britain's More magazine: "It's up to me and my mom to decide if I am partying too much. I'm an angel compared to some of my friends."
