Akshay Kumar, Katrina Kaif in towels!

After doing half-a-dozen films with her including super hits like Namastey London, Welcome and Singh Is Kinng, Akshay Kumar knows everything there is to know about Katrina Kaif.

Especially that she has delicate health and if kept under water for a few hours, she is bound to fall ill.

The duo are currently singing in the rain at a Mumbai studio for Priyadarshan’s De Dana Dan. Akshay, dressed in a thin kurta, and Katrina wrapped in a sexy chiffon sari with a strappy blouse.

But the body heat generated from their steamy togetherness was not enough to keep the actress warm. And Katrina sat in a chair after the first shot, shivering, her teeth chattering, the drenched sari doing nothing to help.

Retakes in the rain followed, one too many, and that’s when Akshay sprang into action. He first ran around the set making sure the air-conditioners were switched off. And then requested Priyan and choreographer Pony Varma to “please look out for Katrina’’ because from past experience, he knew if she stayed wet for too long, she would be down with a fever the next day.

The chivalrous actor then ordered two huge Turkish bath towels, wrapped his heroine in one, himself in the other. “God, he treats me like a baby,’’ muttered Katrina. Something she knew before, but now we know too.
