VAPI — Teenager Prerna Agarwal is autistic and blind. She also happens to be one of India's latest singing sensations, thanks to a 2013 appearance on Indian Idol Junior, a popular television show that gained her international attention.

When reporter Jasvinder Sehgal visits the young singer at her home, he finds her listening to a classic Hindi hit from the 1970s while cuddling her favorite soft toy. "My Teddy loves singing songs," she says. "He loves eating pasta and drinking orange juice. He wakes up earlier than me and also wakes me up every morning."

Prerna then excitedly introduces her family. "My mother’s name is Punita. She is always in the kitchen busy cooking tasty food for me. My father is Umesh, he's a businessman and manufacturer of pens, and this is my brother Piyush Agarwal, an engineering student," she explains.

Prerna's father says he noticed her talent three years ago when one of his friends asked her to perform at a local event. "He was very confident that Prerna would steal the show," says her father Umesh. "She sang a popular religious number. That was her first performance. She sang it so beautifully that she got a thunderous applause and a standing ovation."

Her mother is certain that Prerna will become a professional singer. "She is obsessed with music," her mother Punita says. "You could say that she "eats music" and "drinks music." When she is singing she neither feels hungry or thirsty. The other children demand breakfast when they wake up but my daughter just wants to turn on music."
