Kareena, Kajol and Karan back with K3 magic!

Last time we saw them as loving sisters Anjali and Pooja in Kabhi Khushi Kabhie Gham. This time they are back once again, however not as sisters but 'sautans'. Both of the actresses have been finalized by Karan Johar for his next film. The film is said to be based on Hollywood's "Stepmom" starring Susan Sarandon and Julia Roberts. Kajol would be playing the role of Susan Saradon, and Kareena will take Julia Robert's place.The movie will be directed by Siddharth Malhotra.
