Prem Kumar Gangai Amaren (born 26 February 1979), better known as Premgi, is an Indian playback 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 Venkat Prabhu's films. His stage name, Premgi, is actually a spelling error, as it is meant to be "Prem G.", (the G referring to his father's name). He is also best known for his catchphrases Enna Koduma Sir Idhu ? (What atrocity is this, sir ?) and Evvalavo pannitom, itha panna mattoma (We've done so much, won't we do this also ?), the former being a modified version of a famous dialogue used by Prabhu in Chandramukhi (2005).
