From wiki:

Metta World Peace (born Ronald William Artest, Jr., November 13, 1979) is an American professional basketball player and rapper who is currently with the Los Angeles Lakers in the National Basketball Association (NBA). World Peace gained a reputation as one of the league's premier defenders as he won the NBA Defensive Player of the Year Award in 2004. He was a major participant in the Pacers–Pistons brawl and is known for his sometimes eccentric, outspoken behavior.

World Peace was publicly known as Ron Artest until legally changing his name in September 2011.
