An exotic dancer called The Punisher discovered his client's identity when he turned on a hotel television before an encounter and the screen said, "Welcome Sean Combs".
Sharay Hayes testified at the hip-hop mogul's sex-trafficking trial that he was hired to create "sexy, erotic scenes" with Combs' then-girlfriend Casandra "Cassie" Ventura while a naked man watched from the corner.
But he did not realise at first that the man was Mr Combs. That changed when Mr Hayes was waiting for his clients in a luxury hotel suite and saw his name on the television's welcome screen.
Mr Combs, 55, has pleaded not guilty to racketeering, sex trafficking and transportation to engage in prostitution.
