Shah Rukh Khan and Katrina Kaif gave a glimpse of their sizzling chemistry in their forthcoming romantic film "Jab Tak Hai Jaan" on the sets of "Kaun Banega Crorepati 6" (KBC).

The on-screen couple came together on the sets of KBC to promote their movie, and both looked very comfortable in each other's company. They joked, laughed and pulled each other's leg in the company of Bollywood megastar and KBC host, Amitabh Bachchan.

Following Big B's request, SRK and Katrina danced on a romantic track from "Jab Tak Hai Jaan", late Yash Chopra's last directorial venture, which is set to release Nov 13.

Both the actors moved to the slow beats of the song and their crackling chemistry was a treat to the eyes, said a source.
