London, (ANI): Lindsay Lohan's father has claimed that he knows her daughter buys prescription drugs from one of Hollywood's biggest dealers.

Following on from his previous allegations about his daughter's alleged prescription drug use, Michael says he fears that Lindsay's alleged habit is being fuelled by a drug dealer who dishes out narcotics to other big Hollywood names.

"This guy follows Lindsay all over the place. All over. Lindsay pays for him to go everywhere. He has no job. No job. He does nothing. All he does is supply everyone in L.A," the Daily Express quoted him as telling RadarOnline.com.

Michael recently vowed to help Lindsay beat her addiction. "I'm going to get her off the prescription drugs that she's on... When you hug her she's like, vacant inside. When she kisses or holds me I get chills, and not in a good way - in a bad way. She's a different person," he said.
