AR Rahman is known as a hard worker who works without minding the time of the day. It has been reported that no matter what, he would work until he completes what he is doing. The Mozart of Madras is currently working on his new album 'Raunaq' at his studio. His son Ameen visited Rahman at his studio, to stop him doing work late into the night. The kid was there at 3.00 am to make his dad realize that he is very precious for him and it became very hard for Rahman to convince his little champ. He revealed on a social networking page, that his son Ameen left only after he promised him he would go to sleep. Hope, he fulfilled his son's wish!
