Jackass star Steve-O claims Lindsay Lohan allegedly once stole a bag of cocaine from him.The MTV comic star says the 'Mean Girls' star - who is currently in rehab being treated for drug and alcohol abuse - came to his house and left with a bag of his drugs, which he refers to as a "Boog Suge". Steve-O told shock jock Howard Stern on his Sirius radio show: "Lindsay had left her wallet in my bathroom and she came back to my place to get it and while she was there she took a Boog Suge home with her too."I haven't heard from her since she went to rehab."The 'Jackass' star even has proof Lindsay was at his house because she signed a release form for a DVD he was filming there at the time. Meanwhile, Lindsay's mother Dina Lohan has denied reports her daughter is leaving rehab. A friend of Lindsay's claimed the 21-year-old actress - who entered Utah's Cirque Lodge in August after being arrested on suspicion of driving under the influence - was due to check out at the weekend.When asked to comment on the rumors, Dina said: "It's not true. She is staying in Utah."Lindsay entered the rehab centre following her arrest on July 24 after she crashed her car following a high-speed car chase in Santa Monica. She was in possession of cocaine when she was taken into custody. It was her third stint in rehab. She previously stayed at the Wonderland and Promises facilities in Los Angeles.
