Siddharth Malhotra, Varun Dhawan and Alia Bhatt have been a solid threesome by doing everything together until ‘Student of the Year’ releases! Here they are all seen at the birthday party of Amitabh Bachchan. I don’t really know whether they were invited, but if Karan Johar was the emcee of the event, then I’m sure he quietly arranged for them to appear on the red carpet all nice and ready to promote their film! Also seen is the lovely Deepika Padukone, who played the daughter of Amitabh Bachchan in ‘Aarakshan’. I know that Madhuri Dixit has appeared in one song with Amitabh Bachchan, but I don’t remember them in a film together.
