it might be they are over it by now...coz if we believe the stories and put two and two together it seems its almost a year since they broke up...after all Karan was missing in Kittu's last birthday...(October 25th 2011)...and the news of their split was everywhere...and again karan and kittu are two very open ppl...more so Karan...his life style..his fb and twitter accounts bear witness to the fact that he is very open about his life...kittu might not have been that willing to open old wounds and so chose to stay away from this show...quoting professional reasons...but then i am not convinced that the two are comfortable showing their break up story on TV😕 if it was so painful that is...they would never act to show the same..😒
