Did those 15 takes happen? We think not.
Kala Chashma will be released on Wednesday - the first full-length glimpse of Baar Baar Dekho - and both Katrina and co-star Sidharth Malhotra are intensely excited.
On Tuesday evening, Sidharth tweeted a picture featuring Team Kala Chashma which included director Nitya Mehra, co-producers Farhan Akhtar, Karan Johar and Ritesh Sidhwani, and Katrina.
Teasers of the song, which is a version of the popular Punjabi song recreated by Badshah, have been released daily for the last few days. Here's the latest:
"Kala Chashma has been the most loved song of the Nineties. It used to be one of my favourite numbers too. I am eagerly waiting to see the reaction of the audience for this song. We have worked really hard to put together the enhanced version with full energy," Sidharth said in a statement on Tuesday.
The first look of the song was released last week:
Baar Baar Dekho, directed by Nitya Mehra and co-produced by Karan Johar, is scheduled for September 9.
