Prem Kumar Gangai Amaren (born 26 February 1979), better known as Premgi or Premji, is an Indian singer, composer, songwriter, actor and comedian. The son of composer and director Gangai Amaran, he often composes rap songs in Tamil cinema and is known for his comical performances in his elder brother's films. His stage name, Premgi, is actually a spelling error, as it is meant to be "Prem G.", the G referring standing for Gangai. Wikipedia
