Cudi - born Scott Mescudi.In the interview, the Just What I am rapper opened up about his experience of testifying as a witness in Diddy's recent s*x trafficking trial (which concluded in a partial guilty verdict on July 2).Cudi told the network:"It was really hard. I didn’t want to do it. I got subpoenaed... It was weird, man, because that was the first time I had seen him in a while. We made eye contact a couple times."In his testimony, which took place in June 2025, Kid Cudi alleged that Combs was not only abusive towards Cassie but also broke into his house after learning that Ventura was dating him. Per Mescudi, Diddy also set his car on fire later.The rapper added in his recent interview:"I knew I was helping Cassie. I just wanted to be there and help her out. I know I did the right thing, so that’s all that matters."Elsewhere in the interview, Mescudi also addressed the backlash he faced from Diddy's supporters for his testimony, saying:"I had a lot of people that supported me, but there were a few that had some opinions about it. It was interesting because I’m not no street dude. I don’t live by no code, you know? So I guess it’s because I’m a rapper. People just threw that on me. But, like, my music has never been about that and I have never tried to pretend I was about that."At the end of Diddy's trial, the jury acquitted the rap mogul on three RICO charges he faced, while convicting him on two charges of transporting women for pr*stitution.Kid Cudi also reflected on his complicated relationship with Kanye WestSXSW 2009 Day 4 - Source: GettyIn his CBS Mornings interview, Kid Cudi said Kanye West is his “polar opposite” and called their fallout “really heartbreaking,” expressing sadness over the end of their collaboration.
