The poll conducted in December 2013 saw more than four million people send in their votes selecting the most intelligent, desirable and successful women in 2013-14.
The Indian model-actress, who recently turned 40, thanked her fans and admirers across the globe for the honour.
"The result of this poll was brought to my notice in fact by my well wishers. It is overwhelming to hear that over four million people across the globe have voted and listed me amongst their top choices with such beautiful and talented women. A huge loving thank you to all my well-wishers for making me smile and always being there for me," Rai said.
