Indian actress and former beauty queen Aishwarya Rai Bachchan stunned the world with her sizzling appearances during the 68th annual Cannes Film Festival in France.

In 2012, the 41-year-old Pride And Prejudice actress had faced criticism, from within Bollywood, over her reluctance to shed post-pregnancy weight immediately after giving birth to daughter Aaradhya Bachchan.

However, she has since fought back, and three years on at the Cannes Film Festival 2015, Aishwarya Rai, has stunned critics with her remarkably slim figure.
