As you flock to watch 'Main Hoon Na', you'll out a sultry teacher, who makes every student in her class panting including SRK.

Yes, that is Sushmita Sen for you playing chemistry teacher in Farah Khan's directorial venture. According to Farah she is the one who can teach you the original lesson in glamour.

"After Sridevi, if there is someone who can carry off the sari with grace and élan, it is Sushmita," she declares.

But perhaps Khan is not privy to the all her 'Sen-sibilities'. Ask Mukul Abhyankar and he'll tell you, when it comes to doffing the saree on screen no one dares to beat Sushmita either. Mukul has just signed Sen to play the lead role in his film Dogs', where the bong beauty will be playing a hooker.

According to him, none of the stars including Preity and Rani are cut out to play such complex roles.

'Dogs' is the story of a master-slave relationship where Rishi Kapoor plays a mentally deranged man and Big B is a dog trainer. Sen is a prostitute, whom Kapoor wants to possess instead, she gets attracted to Bachchan and causes bad blood between the two heroes.

If the insiders are to be believed, the leading lady will be having at least one steamy sex scene in the film.

Sushmita's take, "It's certainly not a tame stuff. I always look forward to challenges. Provided there's scope for acting, I don't mind exposing within certain limits. But beyond that it would be difficult."
