Kareena Kapoor is a very karismatic girl, in fact everything her sis Karisma says to her, are words of Gold. Kareena would never have done 'Main Aur Mrs Khanna' if it wasn't for Karisma, simply because time wouldn't permit her. Bebo's schedule was so full, yet she made time for the film. Ask why? Because Bebo had promised her sis long ago that she would do this movie. Main Aur Mrs Khanna was a movie initially for Karisma and Salman, but somehow the movie didn't work out. That's when Lolo (Karisma) had picturized Kareena in the role. And made Kareena promise she'd do this film someday. so down along the line Kareena hasn't forgotten about her promises! Way to go Kareena.
