Katrina Kaif's got the blues and it has nothing to with the men in her life. It's the freezing temperature in London that's giving her the chills. Says a source close to the actress, "Last week, the temperature dropped drastically in London.

Kat has been shooting with Shah Rukh Khan in the city for Yash Chopra's film. She sports a skimpy, sexy look for the film: shorts, skirts and tube tops and the inclement weather put her in a spot. Fearing for her health, the producers wanted to postpone the shoot for a few days and shoot with SRK instead. She would have none of it.

At her insistence, her scenes were shot despite the outfits. She sipped hot ginger tea after every shot." Maybe she should have just called arm candies Salman Khan and Ranbir Kapoor for some natural warmth?
