Karan Johar's birthday party on Monday evening turned out to be an occasion for more than one grand reunion. KJo made sure that Abhishek and Kareena put aside their differences and became friends again.Following the thawing between Abhi and Bebo, the camaraderie between Aishwarya Rai Bachchan and Kareena Kapoor that evening didn't surprise anyone.

To see them laughing, giggling, whispering and behaving like two long-lost sahelis was something that did bring a smile to all the invitees' faces and added that extra zing to Karan's glamour-gorged party.The highlight of the evening was Ash and Bebo taking to the dance floor. Finally, the long-standing cold war between the Bachchans and Kapoors that started when Abhi's relationship with Karisma's sister ended, came to an end. All ties had been severed between the Bachchans and Kapoors.

It was reported that Abhishek refused films with Kareena, prompting the emotional girl to react angrily and defiantly. She publicly snubbed Amitabh Bachchan at an award function last year. Very recently, through the subtle efforts of Aishwarya and Karan Johar from both ends, the two families began to dissolve their differences.KJo's party on Monday evening did the trick. Now it's only a matter of time before Abhishek and Kareena finally come together again for a film after Refugee and Main Prem Ki Deewani Hoon. Chances are KJo will design the project.

Ash and Sonam too had a very brief chat. However there was no lets-be-friends vibe between them, even when they spoke to each other for a few minutes. It was very formal and although Ash was warm, Sonam's stance was aloof. A source reveals, "As soon as Ash spotted Sonam, she rushed to her side and gave her a warm hug. She complimented her on the outfit she was wearing and told her how much she loved her style sense." There was no talk about Sonam being dropped from Cannes at the last minute. Minutes into their conversation, Kapoor spotted someone, she excused herself and walked away.
