Bollywood dainty lass Katrina Kaif refused ‘Krissh 3’ for Yash Chopra’s flick starring Shah Rukh Khan.

Apparently, both Yash Chopra and Rakesh Roshan wanted to go on floor with their upcoming flicks at the same time – October 2011.

Talking to a daily, a source close to the actress said, “Katrina very much wanted to do ‘Krrish 3’. She loved the fact that she would be playing a negative role for the first time in her career. The mutant’s role has several shades which Katrina wanted to toy with.”

It is believed that Katrina’s date diary was already locked for Yash Chopra’s flick by the time she was approached by Rakesh Roshan.

Unable to rope in Katrina, the Roshans approached Chitrangda Singh for the mutant’s role.

When contacted, senior Roshan said, “I haven’t finalised the casting of ‘Krrish 3’. I am still working on the script.”
