The “Pursuit of Happiness” singer, 41, reiterated to host Alex Cooper that he “did not want to do it.” But eventually, he realized that speaking out was a way to support Casandra “Cassie” Ventura, Combs’s on-again, off-again ex-girlfriend with whom Cudi had a brief relationship in 2011.

Kid Cudi opened up about testifying at the Sean 'Diddy' Combs trial, saying, 'I hated every minute of it,' but he was there to 'support Cassie.'

Cudi briefly dated singer Cassie Ventura in 2011 and testified about the abusive nature of her relationship with Sean "Diddy" Combs.
