While Kapil Sharma and Kulraj Randhawa are busy denying their affair, their onscreen chemistry is something that is being talked about.

At the recent shoot in Pondicherry, during the hot shoot of a romantic number choreographed by Pony Verma, the chemistry of the duo was perfect that the hi-speed song was actually a one-take number. "It was not easy," admits Kapil.

"We had to shoot the song in hi-speed and emoting when the song is being heard at hi-speed is not easy. And that too a romantic number."

Nevertheless, the chemistry is very much visible? Says Kapil, "we are actors and it is essential to look the part to the hilt. Yes, Kulraj and I are friends and are together most of the time in dance classes when we are not shooting and in dance classes.

We also have the same group of friends. Hence there is a certain comfort level we share and that is visible on screen."

Kulraj admits to the "comfort level, but sticks to the "Good friends and single and ready to mingle" tagline. Comfort level is cool, but comfort level in romantic numbers? That is something only the "good friends" will tell. Some day. As a unit hand puts it, "They just look so perfect together."
