It's double celebration time in New York - Diwali on Tuesday and Shah Rukh Khan's 40th birthday Wednesday. But there's little time to party with shooting on for Karan Johar's new film and birthday boy also busy with promoting his "Paheli" for the Oscars.

"There's no time to celebrate," bemoans the harassed director Karan Johar, whose new directorial venture "Kabhi Alvidaa Na Kehna" is being shot at full speed in the heart of New York. "We're working round the clock. Diwali is just a thought so far away from home. Wish we were back."

No concrete birthday plans have been made for Shah Rukh's birthday either. "Everyone will probably go out for dinner with Shah Rukh after shooting... that's it," ventures Karan. "Shah Rukh's right now busier than all of us in the unit."

Apart from shooting for Karan Johar's film, Shah Rukh is busy promoting "Paheli in the US for the Oscars. The actor, who turns 40 Wednesday, is going all out to ensure that the film gets noticed in the night places.

"Shah Rukh is making sure that 'Paheli' has a genuinely valid shot at the Oscar and does not get left out of the nominations list for the lack of proper promotion. He's unarguably one of the best producers in Bollywood," says a colleague from the unit.
