Rapper Kid Cudi is expected to take the stand this week in Sean “Diddy” Combs’ high-profile federal sex trafficking trial, according to Complex.

His testimony follows emotional courtroom statements from Cassie’s mother, Regina Ventura, who detailed a disturbing series of events involving the music mogul. Ventura testified that Diddy once demanded $20,000 from her after learning that Cassie had briefly dated Kid Cudi during a break in their relationship. She claimed she took out a home equity loan from her credit union to pay the amount — money Diddy later returned.

Ventura also recounted reading a troubling text from Cassie around that time, in which Cassie claimed Diddy was threatening to release “two explicit sex tapes of her” as retaliation for her connection with Cudi.
