Katrina Kaif has shared screen space both with Shahrukh Khan and Salman Khan and those films became blockbuster hits. Despite working with the two Khans, she feels more comfortable working with Salman Khan than with SRK. Before this statement becomes a controversy, she has cleared that since she knows Salman Khan from the beginning of her career, both personally and professionally she has a comfort level, but this is different with SRK. She also adds, that Shahrukh Khan is a big actor in tinsel town, and that could also be the reason for her nervousness.
