Joining Amitabh, Abhishek and Aishwarya Rai Bachchan were Vivek Oberoi, Kareena Kapoor, Katrina Kaif, Urmila Matondkar and Arshad Warsi with his wife Maria Goretti.
Conspicuous by their absence are the Khans of Bollywood -- Shah Rukh, Aamir and Salman.
Sources say Wizcraft, the event management company which oversees IIFA, is trying to bring at least Salman to the event, apparently even promising the star an exhibition of his paintings.
Whether Salman can make it is anyone's guess as the actor is busy with his latest film, Main Aur Mrs Khanna and his television show, Dus Ka Dum, which goes on air today on Sony.

The event was meant to spread awareness about global warming.
