Katrina Kaif, who will be next seen in a Yash Chopra directed film for the first time with 'Jab Tak Hai Jaan', recently admitted that she was so desperate to work with the veteran filmmaker that she would often pray in church for an opportunity. At a recent event, when she was promoting the movie alongwith her co-stars Shah Rukh Khan and Anushka Sharma, Kaif revealed, "Ever since I had seen 'Veer Zara', I was desperate to work with Yash Chopra. I was so keen on working with him that whenever Aditya Chopra used to call me for some or the other meeting at Yash Raj Studios, I would go to the Mount Mary Church and pray that the call should be for an opportunity to work with Yash-ji." 'Jab Tak Hai Jaan', which is a romantic love story, is slated to release on November 13 this year.
