Sean “Diddy” Combs’ longtime stylist spilled the disgraced rap mogul’s vile and violent secrets Wednesday as he testified at Diddy’s sex-trafficking trial in Manhattan.

Celebrity stylist Deonte Nash, who worked with the Bad Boy Records founder for a decade, revealed new insider details about his threatening nature and then-girlfriend Cassie Ventura’s attempts to escape.

Combs, 55, is accused of using his fame, fortune and many businesses to run a sex-trafficking and racketeering scheme in which he controlled and manipulated Ventura for over a decade, using violence and threats, forcing her and others into drug-fueled “freak-off” sex marathons that went on for days.

He faces life in prison if convicted.

The trial is not televised because cameras are prohibited inside the federal courthouse, but we’re there following all the action — so watch this space for the latest updates.
