Sean Combs (born November 4, 1969), known by his stage names Puff Daddy, Diddy, P. Diddy and Puffy, is an American rapper, record producer, actor, men's fashion designer, entrepreneur and dancer. He won three Grammy Awards and two MTV Video Music Awards.

He was originally known as Puff Daddy and then as P. Diddy (Puff and Puffy being often used as a nickname, but never as recording names). In August 2005, he changed his stage name to simply "Diddy". He continues to use the name P. Diddy in New Zealand and the United Kingdom, the latter after a legal battle with another artist, Richard "Diddy" Dearlove. In June 2008 Combs' representative denied rumors of another name change.

His business interests include Bad Boy Records, the clothing lines Sean John and Sean by Sean Combs, a movie production company, and two restaurants. He has taken the roles of recording executive, performer, producer of MTV's Making the Band, writer, arranger, clothing designer, and Broadway actor. Combs is one of the richest hip-hop performers, having a net worth estimated at US $346 million in 2006.
