It's all very hush-hush and rush-rush. But you really can't keep a killing blend like Shah Rukh Khan, Kareena Kapoor and Priyanka Chopra under wraps.

The lethal trio shot an ad for Pepsi in Madh Island two weekas ago. The ad is being positioned as 'Pepsi TV'.

Says a source, "It basically means ... whenever you're watching television you must have the cola in your hand. That's how the soft drink is being positioned in the market through this ad."

While Kareena and Priyanka have shot another Pepsi ad recently for Farah Khan, throwing Shah Rukh in the feminine brew is deadly, especially since SRK will be seen with both Kareena and Priyanka later this year in Farhan Akhtar's slick-flick Don.

The ad made at an estimated budget of Rs 35 lakhs, was shot by SRK's buddy Farah Khan and produced by his company Red Chillies Entertainment.
