Vidya Balan in her upcoming movie Ishqiya was required to suck on Arshad Warsi’s thumb suggestively and everytime she sucked on Arshad’s thumb she burst into laughter.

Vidya says, “Fortunately Arshad is a friend. We’ve gotten along well from the time we did Lage Raho Munnabhai together. I don’t know I’d have been able to do a scene like putting my co-star’s finger in the mouth with someone else. That gesture of sucking Arshad’s thumb was so raunchy and sexy, so not me, I couldn’t connect with it all.”
