Sajid Nadiadwala's 'Kambakht Ishq' is certainly looking more than promising, what with Akshay Kumar's death defying stunts and Kareena Kapoor's size-zero body in bikinis!

The feisty babe is all set to give her beau, Saif Ali Khan, some sleepless nights as she strips down to a two-piece to get close and intimate with Akshay, who will be luring the lady in nothing but trunks.

While Kareena's two-piece look has been designed by Akki Narula, Akshay Kumar's look has been done by Shabina Khan. The 'Khiladi' wants to give his best shot in the shorts - and, sources say: "Akshay is on a restricted diet for the last 40 days."

The twosome is sure to send temperatures soaring, as they perform some underwater sequences for the film, in the exotic locales of a scenic village in Venice.

To create an underwater effect, a fairly expensive set was put up. A suburban swimming pool was first drained of all the water. Thereafter, a replica of a Venetian lansdscape was created by noted set designers, Acropolis. While the mountains were made of acrylic, the coral for the coral reef was flown in from Venice.

After the set was designed, water was poured back into the pool and a glass chamber was erected so that the film could be shot.
