Imtiaz Ali prefers to be tightlipped about his next project with Shah Rukh Khan. Buzz is that SRK will play a Sikh in the film.

But King Khan dropped a hint about the film's plot over the weekend on Twitter. The star stated: `Revealed Imtiaz Ali story. That you become such an unquestionable part of me, that I can't find the beginning of your heart and the end of mine.`

Imtiaz is known for poignant portrayal of relationships and this looks like a tale of love and longing.
