Sean "Diddy" Combs' ex-girlfriend Cassie Ventura testified in court on her romance with Kid Cudi and how the relationship angered Combs.

During her testimony at his federal trial, Cassie Ventura said that Sean 'Diddy' Combs 'threatened' to 'hurt' both her and her boyfriend Kid Cudi.

In the now-infamous surveillance video showing Sean “Diddy” Combs hitting and kicking Cassandra "Cassie" Ventura in the elevator bank of a Los Angeles hotel, she is seen curled up in a ball as she takes the brunt of his wrath.

Cassie testified Wednesday that she developed a drug addiction from Sean "Diddy" Combs' hours and days-long "freak off" sex parties.
