Master P has taken a leaf out of Sean Diddy Combs book and changed his name.The hitmaker-come-entrepreneur, real name Percy Miller, now wants to be referred to as P. Miller - because it's a more grown-up moniker.Miller has been known as Master P since entering the rap game in the early 1990s but now he says, "I'm changing my name because Master. P is who I used to be. I call it my childhood, and P. Miller marks my manhood... People grow mentally and spiritually through life experiences."The Grammy winner hopes the new name will help him to distance himself from his past as a gangsta rapper.He explains, "When you come from hip-hop it's almost impossible to move past the stereotypes associated with it."I've branched out into so many different arenas that range from being the first African-American to have a clothing line at Wal-Mart to writing books and speaking on Capitol Hill, but all that gets overshadowed because I come from the hip-hop industry."There are a lot of people out there, who are afraid to grow up and change, but I'm not, and P. Miller is the evolution of me, Percy Miller the entrepreneur, the businessman."
