The movie which has Shahrukh Khan, Anushka Sharma and Katrina Kaif in the lead roles, was in the news, since, it marks the directorial comeback of Yash Chopra, after a gap of eight years.

Adding more fuel to it, was the buzz which claimed that Katrina will lend her voice for a romantic number in the flick, composed by Rahman.

However, the Oscar-Grammy winner has denied it. "No, Katrina is not singing any song," he replied, when asked about the claim.
