Sidharth Malhotra is soon going to make his singing debut with Shakun Batra's upcoming film 'Kapoor and Sons'. That's not all, he will be joined by his co-actors Alia Bhatt and Fawad Khan, who are already good singers.

Buzz is that the film has few portions and a promotional song left to be shot. And the director and his team are busy planning out some thing fun and exciting for the special number. It is said that the film's producer Karan Johar has some interesting ideas for the same and once they finalise the concept, they will shoot with the cast.

The song is expected to be a fun with a young and energetic feel; which will match to the film's concept. Since Batra wants to keep it casual and fun, he is not keen to have Sidharth taking any training for singing. They will start the shooting once the actor returns from London, where he is currently shooting for 'Baar Baar Dekho'.
