Manish Malhotra's 50th birthday: When friends turned foes Kajol and Karan Johar crossed paths!

Manish Malhotra's 50th birthday party had the industry's who's who joining in the celebrations. The ace designer had friends dropping by at his residence on Sunday midnight, early Monday morning to wish him a happy birthday. 

And his closest industry buds Kajol and Karan Johar too dropped by at the party. And guess what happened when both of them almost bumped into each other.

Says a source, "Kajol and Karan didn't talk to each other and they didn't even make it awkward for others, especially Manish because he's close to both of them. Both of them were busy in different corners and then Kajol left early while Karan stayed back."

But Kajol didn't attend the birthday bash thrown by KJo for Manish! Wonder why? The answer is quite simple!
