Katrina Kaif talk about chemistry: Akshay Kumar & Katrina kaif: Bollywood beauty Katrina Kaif, whose sizzling chemistry with co-star Akshay Kumar in Farah Khan's latest offering 'Tees Maar Khan' has grabbed eyeballs, says it comes from years of working together and nothing else.

"Its the familiarity that works. I have spent about 500 days or so shooting with Akshay in the last five years and I think there is no secret to our chemistry. Its good because Akshay has that certain amount of trust and confidence in me," Katrina said. The hit Bollywood pair was liked by audience in many films like 'Humko Deewana Kar Gaye', 'Namastey London', 'Welcome', 'Singh is Kinng' and 'De Dana Dan'.

"In the first year Akshay was like ...Hi, good morning want a hug. In the second year, it was good morning. Third year was morning. Fourth year, it was a smile and now it is 'What's the shot'. We trust and respect each other. Also, now that we are familiar with each other so we tend to drop all the formalities," the 26-year-old actress said.
