Sonu Nigam (born July 30, 1973) is a Bollywood film singer, born in Haryana, India. He modelled his singing style after Mohammad Rafi.

Nigam's first major song was Acchha Sila Diya Mere from the movie Bewafaa Sanam. His big break came in 1997 with the film Border, directed by J.P. Dutta. The film was scored by Anu Malik and the lyrics were written by Javed Akhtar. Nigam's duet with Roop Kumar Rathod, Ke Ghar Kab Aaoge, is especially memorable. He tried his hand at acting as well, but all movies in which he acted flopped.

Since then, Nigam has sung in many Bollywood movies. He also sings duets with fellow Bollywood playback singers Alka Yagnik and Udit Narayan. In addition to his playback work, Nigam also enjoys a successful Indipop career, and has released several albums. In June 2005, Sonu announced that he will not be living with his wife, Madhurima, any more. During a concert in Kabul, Afghanistan on July 20, 2005, his concert stage collapsed but Nigam was left with only a back strain. Since 2004 he has participated as a judge in Indian Idol, further endearing him to the Indian masses.
