Sean Diddy Combs reportedly disciplined a member of his staff after they stole Pharrell Williams personal details and began to harass the hip-hop star.The N*E*R*D hitmaker was baffled to suddenly field emails from a wannabe musician desperate to work with him - so he traced them back to Diddy's Sean John fashion label.A source tells the New York Post, "A Sean John employee got his hands on Pharrell Williams' e-mail address somehow. He e-mailed Pharrell so many times asking if they could work together, but Pharrell had no idea who the person writing to him was."A representative for Combs confirms the story to the Post - but insists the star wasn't involved: "Diddy was not made aware of this incident. A staff member was contacted, and they handled it internally."
