A-list stars who partook in Sean "Diddy" Combs' "freak off" parties now face an ultimatum to either settle out of court or face a lawsuit.

Numerous lawsuits have been filed against Diddy by people claiming to have been assaulted by the star, and the lawyer representing many of those victims says he is now also reaching out to other celebrities that he believes were involved.

The fallen rapper, behind bars on sex trafficking charges, is accused of throwing wild, alcohol and drug fueled gatherings that devolved into “freak offs,” often involving sex workers and, some allege, minors.

Diddy’s high-profile “freak off” guests face legal action even if they did not participate in the alleged abuse.

An anonymous sexual abuse accuser has been told she’ll have to be named publicly if she wants her suit against Diddy to move forward.
