In 2000, Bhansali and music director Ismail Darbar offered her the opportunity to be the voice of Paro, the lead female character of "Devdas", who was portrayed by Aishwarya Rai. Ghoshal sang five songs in the film, namely, "Silsila Ye Chaahat Ka", "Bairi Piya", "Chalak Chalak", "Morey Piya", and "Dola Re Dola", with established singers such as Kavita Krishnamurthy, Udit Narayan, Vinod Rathod, KK, and Jaspinder Narula. She was sixteen when she recorded the first song for the film, "Bairi Piya" with Udit Narayan. Her Higher Secondary Examinations were nearing that time and she would take her books and notebooks to the studio to study during downtime.
