Mumbai: Shah Rukh Khan may share a cold vibe with Salman Khan but he finds ‘Dabangg’ star’s pairing with Katrina Kaif “wonderful” in ‘Ek Tha Tiger’.

“I don’t know about the chemistry. But they make a wonderful pair. They have done films together and I wish them luck,” Shahrukh said when asked about the chemistry of Salman and Katrina in their soon-to-be-released film ‘Ek Tha Tiger’.

This is for fourth time when Salman and Katrina are coming together on silver screen after ‘Maine Pyaar Kyu Kiya’, ‘Partner’ and ‘Yuvraj’.

“It is very nice…They (Salman and Katrina) have done movies together in the past. I think chemistry is a too deeper word, that was created by media. Even Kajol and I had issues with (the word) chemistry,” SRK said on the sidelines of Tag Heuer event, for which he has been brand ambassador since decade.

“It has taken me years to understand what this chemistry is. When I came back with 20 years of work, you keep asking me about this chemistry…It is so loosely used,” he added.

Directed by Kabir Khan, ‘Ek Tha Tiger’ is a romantic-action thriller. Produced by Yash Raj Films, the movie releases on August 15.
