Aishwarya Rai and Hrithik Roshan are all set to sing for a track in Sanjay Leela Bhansali’s Guzaarish. The song will be recorded by director Bhansali who is also composing the film’s music.
This is the first time Hrithik Roshan will croon for a film. As for Ash, Shah Rukh Khan and she memorably sang the track Apun Bola Tu Meri Laila for Josh. Of course, there are reports that she will be rendering a song for Mani Ratnam’s Raavan too.

Rumour has it that Hrithik Roshan and Aishwarya Rai-Bachchan will be singing in Sanjay Leela Bhansali's Guzaarish.
Bhansali, who composed one song in his last film Saawariya called Thode badmash ho tum, will compose music again.

He urged the lead actors to sing for the number and apparently, they have agreed.Though Ash did sing Apun Bola years ago in Josh, Hrithik hasn't ever sung for any of his films. Perhaps Bhansali thought this would add to the novelty factor of the rather heavy drama film - where Hrithik plays a paraplegic who wants the court to let him end his life.

While the Hrithik Roshan - Aishwarya Rai pairing was always going to be one to watch out for — especially after their sizzling Dhoom 2 chemistry — this just makes it all the more interesting.
In Guzaarish, Hrithik plays a paraplegic suffering from impairments of the motor and sensory functions of the lower limbs. Aishwarya Rai plays his nurse in the movie and the duo are learning Portuguese for the film too.
