Kareena Kapoor Birthday: The superstar recalls how she was more focused on Tashan and achieving `size zero` while simultaneously shooting for Jab We Met. She claims that she was more invested in Tashan than in Jab We Met. As fate would have it, Jab We Met went on to become a classic romantic film and one of the most loved movies in Bollywood. It completely overshadowed Tashan. According to director Imtiaz Ali, the movie had to be shot as soon as possible because Kareena`s availability was an issue, so the movie had to be made while she was preparing her size zero body for Tashan.
