Sean “Diddy” Combs’ ex-girlfriend, Cassie Ventura, began what could be a days-long testimony in Combs’ sex trafficking trial Tuesday, alleging on the witness stand Combs had subjected her to physical abuse and coerced her to participate in “freak off” sex performances. (Here is a complete list of the allegations against Combs).

Combs, 55, is being tried on charges that he exploited his status as an entertainment executive to force women into drug-fueled "freak offs" with male sex workers and engaged in other abusive acts against people who relied on him for their careers.
