Both Cudi and Cassie testified against Diddy during his trial back in May. Diddy, who denied all charges against him, was arrested on sex trafficking and racketeering charges in September 2024 and was found guilty on two counts of transportation to engage in prostitution on July 2.

Kid Cudi was subpoenaed during the Sean "Diddy" Combs trial. During testimony, he felt he had to "look out for" Cassie Ventura, who had been "living a nightmare."

Kid Cudi opens up about his early career, substance abuse struggles, redemption and relationships in "Cudi: The Memoir," out now.
