A lot goes into being the top Bollywood actress and maintain the standards of the work without any excuses. That is exactly how Katrina Kaif is leading her life in Bollywood. 

She has been at top of her game in the last few years. And this race to be on top is now taking a toll on her as she has not been in the pink of health in recent times. 

The actress who has been shooting for Kabir Khan's 'Phantom' with Saif Ali Khan, and Siddharth Anand's 'Bang Bang' with Hrithik Roshan, was shuttling between Prague and London for the same. 

She has been working for 50 days back-to-back without any break. And hence by the time she recently returned to Mumbai, she had completely exhausted herself. 

Apparently, the actress had to shoot for a promotional video for 'Bang Bang' in which she was supposed to be in top shape. She was working out for long hours and was on a strict diet. All of this left her weak and immune to sickness. 

Eventually a day before the shoot, Kat fell sick and was advised bed rest for the following day. Due to this sudden fall in Katrina's health, the shoot was cancelled. 

The shoot has now been rescheduled for the end of the month.
