Two Other Accusers Joining Tamara Green's Defamation Lawsuit Against Bill Cosby

Linda Joy Traitz and Therese Serignese are joining Tamara Green‘s defamation lawsuit against entertainer Bill Cosby, her attorney tells PEOPLE exclusively.

“We certainly welcome other people standing up to Bill Cosby to redress harm caused to them by statements made by Mr. Cosby through his lawyer and spokespeople,” Joe Cammarata, Green’s attorney, tells PEOPLE.

Cammarata filed the amended complaint Monday, he says.

Green, 56, filed her lawsuit against Cosby on Dec. 10 in Springfield, Massachusetts, not far from where Cosby owns a home. She says his representatives defamed her in comments they made to Newsweek and The Washington Post last year.

“We are very confident that we will prevail in this proceeding and we will pursue claims against the attorneys who filed this action,” Cosby’s attorney, Martin Singer, told PEOPLE following Green’s filing.

Green, a retired attorney who lives in Southern California, alleges that Cosby drugged and sexually assaulted her in 1969 or 1970, when she was an aspiring model. CLICK FOR MORE
