Charlie Sheen is being sued for $20 million.
The former 'Two and a Half Men' star has been accused of destroying a planned reality TV project about himself and his family by a television producer working with his estranged uncle, Joe Estevez.
Ed Meyer claims the 45-year-old star conspired to intentionally interfere with contractual relations and alleges his parents, 'West Wing' star Martin Sheen and his wife Janet, acted as "co-conspirators" in killing the programme.
However, they were not named as co-defendants.
The suit - which was filed in Los Angeles County Superior Court on Tuesday and used Charlie's birth name Carlos Irwin Estevez - claims: "Starting on January 4, 2010, Defendant Carlos Irwin Estevez, along with co-conspirators Martin Sheen and Janet Sheen, all non-parties to the Reality Show deal, did internationally and tortuously: threaten, interfere with and restrain, and also conspire to: threaten, interfere with and restrain the Plaintiff's reality television project starring their relative Joe Estevez, titled: 'About The Sheens' aka 'Being Sheen' aka 'Sheen Reality,' thus destroying the contractual relationships and damaging the Plaintiff Ed Meyer."
Ed is seeking at least $20 million in damages "for the outrageous tortuous conduct" of Charlie.
Earlier this month, it was revealed Charlie is suing 'Two and a Half Men' producer Chuck Lorre for $100 million, claiming he was unfairly dismissed from the show.
Joe is the younger brother of Charlie's father.
