Katrina Kaif is all about work and she's showing it! Katz was so involved in promoting all of her three films at once that she came down with a bitter fever. But this didn't bring her down, no not at all. Katrina was up and atom promoting De Dhana Dhan as soon as she recovered! We have to admire her spirit, but we hope that she doesn't overdo it, for health reasons that is.
