Shahrukh 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.
KJo is very close to Adi, respects and loves him, but its Udi boy who is his back-slapping yaar. SRK and Adi...are you feeling left out, dearies? C'mon, its all about loving the family, remember? Apparently Uday talks to Karan about everything...movies, women, etc in fact he doesn't sign any film without discussing it with KJo. May be Karan is the one man who can add a little 'dhoom' to Udi boy's film career. Dosti ke khatir.... what say?
