Kareena Kapoor threw a party last night at her residence to celebrate the release of her movie Ki and Ka. There were many B town celebs who attended the party including Malaika Arora Khan who recently separated from husband Arbaaz Khan. Few Minutes after Malaika came in, Arjun Kapoor walked in too. The most surprising thing was that Karisma Kapoor too was present there with her rumored boyfriend Sandeep Toshniwal, who has been with her post her bitter separation from Sanjay Kapur. But hey, what's the deal between Malaika and Arjun Kapoor.
