Sean "Diddy" Combs' alleged abuse of former girlfriend Cassie Ventura Fine continues to be exposed in court as additional witnesses testify.

A former assistant to Sean “Diddy” Combs, Cassie Ventura’s mother and an exotic dancer nicknamed “The Punisher” all testified during Combs’ federal criminal trial on Tuesday as the prosecution continued to make its case against the hip-hop mogul.

Regina Ventura, mother to R&B singer Cassie Ventura, described screaming at Sean "Diddy" Combs after he took control of her daughter's cellphone.

Combs threatened singer Cassie about the tapes via email, according to Cassie's mother, Regina Ventura, in her testimony Tuesday.

Cassie Ventura's mother took the stand to testify in Sean "Diddy" Combs' racketeering and sex trafficking trial. She testified about alleged abuse and blackmail that her daughter suffered. Combs has pleaded not guilty.

Diddy's sex-crimes trial is expected to take a star-studded turn as Kid Cudi is called to testify. The rapper was once romantically linked to Cassie.
