"I have learned singing from my mom and I don't plan to give it up because I am very passionate about it," said the newcomer in a statement.
Coming from an illustrious musical family, she informed: "Musicians Sajid and Wajid are my maternal uncles. My stepsister is the famous English singer-songwriter and multi-instrumentalist Natasha Khan, who goes by the stage name Bat for Lashes.
"My great grandfather was Jugal Kishore Mehra, who was Raj Kapoor's uncle and married to Anwari Begum, the famous singer. My grandmother Nusrin Agha, was a well-known singer as well. So in a way, I am the fourth generation singer in my family," she added.
Sasha has already recorded the song.
A source close to the film said that producer Aditya Chopra managed to convince Sasheh to sing a peppy number titled "Barbaadiyaan", a club track filmed on Sasheh and Arjun Kapoor.
A spokesperson from Yash Raj Films confirmed the news, saying: "Yes, Sasheh has sung this beautiful track (for the film). Her voice is as melodious as her mother's."
Salma debuted in Bollywood in 1982 with box office hit social drama "Nikaah" and she sang all her songs in the film, including the hit number "Dil ke armaan aansuon mein beh gaye".
