Nikhil Advani and Karan Johar
It looks like Karan Johar has no paucity of friends-turned-foes. Nikhil Advani and KJo parted ways after completing their successful film together 'Kal Ho Naa Ho'. Their split was a big shock for everybody in the industry as both the men were known to share an excellent rapport with each other. However, over time the men mended their ways and got back together. In fact when Karan Johar was harbouring some problems before the release of 'My Name is Khan', Nikhil logged on to a micro-blogging to express his support for the film-maker.
