Bisexual actress Lindsay Lohan failed to turn up on the set of new movie Scary Movie 5 because she claimed to be suffering from 'walking pneumonia'.
The Hollywood star who has been plagued by drugs and legal problems reportedly skipped filming in Atlanta to avoid a scene in which her troubled past was mocked.
'Lindsay missed every meeting she had for the film, including script reads and wardrobe meetings,' a Hollywood source told the New York Post, adding she had been 'freaking out' about the spoof sequel.
The insider added: '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.
'She is under contract - so to get out of it, she had to prove that she was sick. She tried to prove she has walking pneumonia.'
The 26-year-old is also allegedly distressed about having to kiss co-star Charlie Sheen - an actor who has also struggled with addiction - during a scene which clearly pokes fun at her.
However, Lohan's representatives have denied the rumors, stating that the actress is 'willingly fulfilling all of her obligations.'
