Cassie will testify against Diddy in his upcoming trial. Cassie Ventura will reportedly use her real name in the upcoming trial against Sean “Diddy” Combs. As People reports, a motion was filed on April 4 identifying Ventura as “Victim-1” of Diddy’s upcoming trial, which will see him face charges for sex trafficking, transportation to engage in prostitution, and racketeering. Reportedly many of the witnesses testifying will do so under fake names, but not Cassie who famously dated the rapper/mogul for years.
