First up, a picture with Aishwarya Rai Bachchan, 21 years after they were competing beauty queens. In 1994, Aishwarya lost the Miss India title to Sushmita. Both went on to win the Miss World and Miss Universe pageants. Since then, they have each pursued careers in Bollywood, Aishwarya with greater success than Sushmita. Gossip has long subscribed to a rivalry between the actresses although neither has provided the public with any indication that there might be any truth in it.

At the party, Sushmita couldn't get her eyes off a Dhoni - Ziva, 10-month-old daughter of MS Dhoni and Sakshi, who were also on the guests list.
Then there was a picture with her 'two favourites' - her Bas Itna Sa Khwab Hai co-star Abhishek Bachchan and director David Dhawan, whose film Biwi No 1 was Sushmita's first big hit.
And finally, Sushmita also posed for a picture with the newly married Harbhajan Singh and Geeta Basra, for whom the Ambanis were hosting the do. Sushmita had only compliments for Harbhajan and Geeta:
Sushmita Sen was last seen in Bengali film Nirbaak.
