Charlie Sheen is usually the wild one on set, but this time it appears that Charlie met his match in Lindsay Lohan.

They were both spotted on the set of "Scary Movie 5" in Atlanta, Georgia, for the first time yesterday after signing up to make cameo appearances in the franchise.

In detail, Lohan wore a pink robe, covering a black nightgown and later revealed a lacy black negligee underneath.

Sheen, 47, kept himself occupied between takes with a game of catch and onlookers spotted one of his assistants delivering a pack of Coronas to his trailer.

Both stars are famous for their bad behaviour and looks like Lindsay has already been a mess for film executives.

Lohan, who has battled alcohol and drug addiction in the past, allegedly tried to avoid a scene ridiculing her troubles, so she missed her flight to the set in Atlanta on Sunday and went to hospital claiming to be suffering from "walking pneumonia".

A Hollywood insider told the New York Post newspaper: "Lindsay missed every meeting she had for the film, including script reads and wardrobe meetings. 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."

Lindsay is considered to be particularly worried about the horror spoof's script, which features a kiss with co-star Charlie Sheen, because of how much it pokes fun at her. 

A source added: "It went pretty hard at Lindsay. She'd been freaking out about it for weeks."

Another insider told the publication: "She's been locked up in her room at the Bowery Hotel. She's been in a tailspin. Even Charlie Sheen worried she might not be able to do the scene."

But a representative for Lindsay states she has been "willingly" completing all her obligations for filming.

They explained: "These stories are untrue, and she is willingly fulfilling all of her obligations."

If Lindsay is well, why does she miss her flights and appointments? Why does she constantly excuse herself for not doing what she is supposed to do? The irony here is that all complain for her behaviour except for her and her reps. It is obvious that this girl needs to take a break...What do you think?
