Hours after porn star Capri Anderson described her infamous night with Charlie Sheen on "Good Morning America,' Sheen filed a lawsuit claiming she's trying to extort him, RadarOnline.com reports.

During her TV appearance early Monday, Anderson claims Sheen threw a lamp at her and grabbed her by the throat. The adult film star plans to file charges against the 'Two and a Half Men' star, according to her attorney. She is suing for battery, assault and false imprisonment.

In his own lawsuit filed late Monday, the 'Two and a Half Men' star states Anderson is trying "an attempted shakedown and extortion of the internationally known actor and celebrity Charlie Sheen." He goes on to describe her as "an opportunistic pornographic film star and publicity hungry scam artist."

Sheen also alleges that Anderson is merely out to get famous. He states in the suit: "after a consensual encounter with Sheen in the Plaza Hotel on the evening of October 25, 2010, [Anderson] decided this was her chance to become rich and famous."
