We've all heard about Karan and Adi's dosti ke kissey over and over again. But there is another hissa to this, and no lovelies, it's not Shah Rukh Khan. It's true that the trio are friends for life, they are one big family, et al (sounds like a KJo movie, na?), but a lesser known fact is that Karan Johar and Adi's chhota bhai, Uday Chopra are best buddies.
