At a time when actresses are turning producers and singers, Kareena Kapoor prefers to steer clear from doing such stuff.
She feels her passion is acting and she should focus only on that.

More importantly, Bebo is clearly not interested in any part of filmmaking apart from acting. That's smart considering Bebo is pretty good at acting.
