Last week Karan Johar played the catalyst, making Shahid Kapoor and Kareena Kapoor not only acknowledge each other’s presence but actually strike up a conversation, and a pretty warm one at that.

The venue for this patch up was Shah Rukh Khan’s bungalow, Mannat, where King Khan had hosted a celebration for My Name Is Khan. Says a source, “Shahid and Kareena came face to face and everyone thought they would simply ignore each other like they have on so many occasions in the past.

But this time, Karan happened to be present right there and instead of marching past each other, they slowed down for a bit. And the rest, as they say, is history.”

Even after the ice was broken, neither Shahid or Kareena seemed in a rush to get back to more comfortable company. They had a pretty warm exchange and a little later even Saif, who was present at the party, joined them.

“Shahid and Kareena have finally decided to leave their acrimonious past behind them. This was very evident in the manner all three of them - Shahid, Kareena and Saif - interacted with each other at Shah Rukh’s party,” adds our source.

While both Shahid and Kareena could not be reached for comment, Kareena’s official spokesperson said, “Kareena has no problem with anybody, including Shahid.” For the record, Shahid and Kareena, who were in a serious relationship for three years, parted ways in 2007, a few days before Imtiaz Ali’s Jab We Met hit the theatres.
