Bipasha Basu along with close friends Rocky S and Dino Morea attended R Madhavan's birthday party on Monday. However, if sources are to be believed she chose not to interact with her former flame, Harman Baweja at the event. An onlooker says, "Madhavan called his co-stars and friends from the industry to celebrate his birthday as well as the success of his latest release, 'Tanu Weds Manu Returns'."
