Kaho Na Pyaar Hai
Hrithik Roshan was supposed to sing Kaho Naa Pyaar Hai to Kareena Kapoor, instead of Amisha Patel! But in an extremely disappointing display of unprofessional behaviour, Kareena walked out of the film after shooting for a few days. Lucky for Ameesha Patel, she became a huge star post the success of the film.
