What Katrina Kaif drank before the Kala Chashma song

Katrina Kaif’s washboard abs have become the-talk-of-the-town thanks to her Baar Baar Dekho song Kala Chashma that has her showing off her midriff.

We hear that the actress follows a special diet before doing any dance numbers. Says a source, “Katrina is particular about her diet. She starts her diet three weeks before shooting for a dance number. While shooting for Kala Chashma she was completely on a no carb-diet — in fact, almost a liquid diet. Her lunch and breakfast comprised juices, soups and broccoli. And before shooting for the song, she only had buttermilk which kept her energised.”

Now, you know her secret.
