They have been professional rivals ever since they started their modelling days. While Sushmita always had a one up when it came to modelling and beauty contest (Sushmita pipped Aishwarya to win a chance to represent India at Miss Universe), Aishwarya has always been the far bigger star whenever it came to brand endorsements (Aishwarya had famously replaced Sushmita as Kalyan Jewellers brand ambassadors after the brand chose not to renew their contract with the latter.) Even on the acting front, Aishwarya has always been the bigger star while Sushmita's career always hung in doldrums. Now with adman Prahlad Kakkar managing a casting coup of sorts by signing both Aishwarya and Sushmita for his directorial Bollywood venture, Happy Anniversary, the nation eagerly awaits to see how these one-time former rivals will get along with each other. Although Sushmita has gone on record to state that there is no real rivalry, she doesn't really chit chat with Aishwarys Rai as one would expect friends to do. When we asked Sushmita at a recent event if she has spoken to Aishwarya in recent times, Sushmita bluntly replied, "I don't chat with Aishwarya. But we are doing a movie together." Wonder what Aishwarya has to say on this.
