LiLo Balks at Role Mocking Her Druggy Past

It looks like Lindsay Lohan isn't yet ready to make light of her troubled past (or present, depending on who you believe). She's set to do a cameo role alongside Charlie Sheen in Scary Movie 5, but apparently had a change of heart after she read the script and realized it poked fun at her well-publicized addiction and legal issues. She also may have been put off by a kissing scene with the Warlock himself. Sources claim that LiLo has bailed out of all the pre-rehearsals and missed her flight to the set, only to show up at the threat of a lawsuit by a Hollywood legal team. "Lindsay missed every meeting she had for the film, including script reads and wardrobe meetings,” said a Hollywood insider. “Then she missed her flight to Atlanta on Sunday to shoot the movie. The producers had been getting signs Friday that she was a mess, and would not be fit to work.” Lohan tried one final attempt to get out of the film by claiming she had walking pneumonia and entering a hospital last weekend to get her lungs checked, but was not able to prove she had the illness in order to satisfy producers. She has reportedly been locked up in her hotel room and sources claim she is in "a tailspin" at having to shoot the scenes. A rep for Lohan is denying the allegations and said that, “These stories are untrue, and she is willingly fulfilling all of her obligations.”
