Kid Cudi, a key witness in the sex trafficking trial against hip-hop mogul Sean “Diddy” Combs, revealed in a new interview published Wednesday that he declined to testify twice before he was ultimately subpoenaed.

Mescudi, who briefly dated singer Casandra “Cassie” Ventura in 2011, said he was asked twice to testify in the trial and declined both times. The government then subpoenaed him, leading to his explosive testimony where he described Combs as “a Marvel supervillain.”
