Mumbai: Katrina Kaif had to finally turn down good friend Ayan Mukherjee's untitled film. Ayan, who is close to both Ranbir Kapoor and Kat was very keen that she should be a part of the project along with Ranbir.

She was also keen and tried her best to accommodate the dates but it was not possible, since she seems to be on a yo-yo with her two films with the Khans -- Ek Tha Tiger with Salman and Yashraj's untitled film with Shahrukh Khan.

Apparently Karan Johar, the producer of Ayan's film, sat with good friend Aditya Chopra to somehow get some dates out but it seemed impossible. Finally, Kat had to reluctantly give up Ayan's project.
