"This case involves a shakedown and extortion of the internationally known actor and celebrity Charlie Sheen ... by an opportunist pornographic film star and publicity-hungry scam artist," the lawsuit states.
The lawsuit, which was filed Monday in Los Angeles Superior Court, further claims that Anderson (real name: Christina Walsh) "fabricated a sensational tale about being assaulted, battered and held against will" and then threatened tell the media "her false tale" if the Sheen didn't pay.
Anderson filed a criminal complaint against the actor earlier Monday, accusing him of battery and false imprisonment. The 22-year-old also appeared on Monday's Good Morning America, where she said she was hired only to escort the Two and a Half Men star to dinner last month, but later retreated to his hotel room, where Sheen lost control. She said Sheen grabbed her neck and that she feared for her life. Sheen later voluntarily checked himself into a hospital for psychiatric evaluation.
"He was, from the beginning of the night, very loud and he had no hesitations when it came to using derogatory language or cuss words," she told ABC News. "But it wasn't until he put his hands around my neck that I really thought to myself, you have gotten yourself in a bad, bad situation," she said.
Anderson's attorney, Keith M. Davidson, denies that his client tried to extort Sheen.
"It's a blatant attempt by them to muddy the waters and confuse the situation," he told People. "They are throwing a bunch of mud at the wall and hoping something will stick."
An email to Sheen's attorney, Yale Galanter, was not immediately returned.
