Though Kalki Koechlin has starred in romcoms like Zindagi Na Milegi Dobara and Yeh Jawaani Hai Deewani, the Dev D actress will be playing a comic role for the first time. She will be seen as a clingy and scheming girlfriend in Happy Ending. (Didn???t she also do that as Abhay???s Deol???s girlfriend in Zindagi Na Milegi Dobara) also starring Saif Ali Khan. Says a source, ???In the film, while Saif thinks they have broken up, Kalki doesn???t acknowledge that and continues to believe they???re in the relationship.??? Wonder if her hubby Anurag Kashyup went through the same thing when she told him that she wanted out of the marriage. Whatever the case, they worked it out and now they are friends. Now that???s a happy ending!
