It is not the afterglow of her relationship with Saif Ali Khan, or the countless compliments for her performance that has gave her new radiant look. The radiant new look is the result of a rigorous work out and dieting session. But that radiant glow cost to her health. The seemingly fit actress collapsed on the sets of Tashan recently. Apparently, she was required to wear a bikini in one scene, which called for a perfect body. Kareena stopped eating and survived on a diet of orange juice. The hectic shooting schedule and dieting took a toll and she collapsed while, ironically, shooting the bikini scene. However, Kareena dismissed rumours of being anorexic, by stating she has lost weight doing power yoga and by sticking to a balanced diet.
