After a tense first week, Sean "Diddy" Combs lawyers finished their cross-examination on the prosecution's star witness, his former girlfriend Cassie Ventura. Combs faces charges of racketeering, sex trafficking and transportation to engage in prostitution. The rapper has denied all of them.

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.

On the stand in court Tuesday, Cassie alleged Combs would "bash my head, knock me over, drag me, kick me, stomp me in the head if I was down."
