NEW YORK (Reuters) -Sean "Diddy" Combs routinely beat his ex-girlfriend and during fits of rage threatened to release sex tapes of her to the internet, a stylist testified on Wednesday at the hip-hop mogul's sex trafficking trial. Deonte Nash, who worked as a stylist for Combs and Combs' former girlfriend Casandra Ventura from 2008 to 2018, alleged that Combs repeatedly beat Ventura and threatened to release the tapes while raging at her for not being obedient. Combs, 55, has pleaded not guilty to five counts including racketeering and sex trafficking.
