Actress Parineeti Chopra, during an appearance on The Great Indian Kapil Show, said she "immediately" gained 15 kg to look like Amar Singh Chamkila's wife and singer Amarjot Kaur in his biopic. "There is no fun in looking like your own self in a biopic...Amarjot performed at shows during her pregnancy, and I had to look the part," Parineeti added.
