Cassie Ventura testified in Sean “Diddy” Combs’s sex-trafficking trial, detailing years of alleged abuse and “freak-offs” with male escorts.

Casandra "Cassie" Ventura is opening up about why she participated in the "Freak Offs" — hours-long sex parties where she alleges her former boyfriend Sean "Diddy" Combs forced her into sexual activities with other men.

Thursday's testimony and evidence was in contrast to the violence and shame Cassie said accompanied "hundreds" of her encounters with male sex workers that Sean "Diddy" Combs watched and controlled during their relationship.
