After two days of testimony about how her relationship with Sean "Diddy" Combs grew violent and coercive, Cassie Ventura faced six hours of grueling cross-examination on Thursday, as defense attorneys attempted to cast doubt on her credibility and portray her as a willing participant in their sexual activities.

Ventura is the prosecution’s star witness, and her testimony Tuesday and Wednesday alleging her ex-boyfriend Combs physically and sexually abused her is key to the charges against the hip-hop mogul.

Cassie revealed both she and Combs struggled with drug addiction, including a 2012 overdose by Combs.
