The government calls Cassandra Ventura.” With those five words, the prosecution dove into the heart of the racketeering and sex trafficking case against Sean “Diddy” Combs – the testimony of his former longtime girlfriend.

For six hours on Tuesday in a Manhattan courtroom, Cassie Ventura testified about how her decade-long relationship turned violent with then-boyfriend, Sean "Diddy" Combs.

The singer broke down crying in court as she discussed Combs' "freak offs," a term for the mogul's alleged drug-fueled sex parties. She said that they made her feel "horrible" and "worthless" but that she continued to participate for "the one-on-one time" with Combs and out of fear that the rapper would become violent or find someone new.
