Lindsay Lohan has reportedly been hitting out at her celebrity friends while in rehab.

A source claiming to be a friend of Lindsay’s told the News of the World: “On the first night she couldn’t stop crying. Since then she’s refused to follow the rules and keeps having hissy fits about people.”

“In one of her group meetings she yelled that her friend [Paris Hilton] was a coke whore and couldn’t believe how stupid she’d been driving while banned. She said, ‘Paris thinks she’s above everyone. She’s not. Paris is a stupid cow and deserves what she gets’.”

“[Next] she saw a woman who is bulimic and said, ‘She’s like [Nicole Richie]. What problems does Nicole have? The girl just needs to eat. Period’.”

But her most bitter venom has been reserved for herself: “She cries all the time at what a mess her life has become and how she has behaved like a complete tart. She just got so carried away with bedding men like Jude and James Blunt she couldn’t stop going out.”

“She was hooked on pulling those kinds of men and took drugs to give her the confidence to approach them. She needs help to stop her obsession.”

“The clinic even took her mobile from her to make sure she can’t call people who are a bad influence on her. But she went berserk so they gave her a new phone with only the numbers of her family, publicist and agent on it.”

“Now her friends just want her to stay in rehab for as long as possible. Only then will she be safe.”
