Birthday Special: Nandana Sen's HOTTEST avatars

The stunning actress turns 47 today.

Nandana Sen, who tied the knot in June last year with Penguin CEO John Makinson, thinks she's more of a nerd than a hottie.

While we all know of her impeccable educational background -- she studied literature at Harvard and topped her class -- it wouldn't be entirely fair to discredit her gorgeous looks!

Here then, is a look Nandana Sen's HOTTEST onscreen avatars, as she celebrates her birthday today.

Donning yet another rustic belle look, the birthday girl hots up the screen in Tango Charlie.

The actress is quite a sight as she lays elegantly, wearing a knotted blouse and beige sari.

The actress flaunts her washboard abs and natural curls in this still from Rang Rasiya.

Looking breathtaking in this particular shot here, the actress sure knows what angles work best for her!

Indian clothes can be unforgiving to women's bodies.

Nandana could teach them all a thing or two about doing it the elegant way.

It takes a lot of sweating out in the gym and confidence to carry off a sari.

And Nandana seems to be a perfect model for the whole nine yards.

Taking the ramp by storm, here's the birthday girl making heads turn as she showstops at the 2010 edition of Lakme Fashion Week.

On a scale of zero to Maxim cover girls and pin-ups, just how desirable is Nandana Sen, you ask?

The results would be off the charts for this one.
