There's no business like show business.

There's also no other profession that makes it imperative for celebrities to look their best, defy age even, if need be.

The fact that some of the most stunning women in the filmi circuit are much older than they look amazes us. We take a look at some of these age-defying stunners.

Nandana Sen

The beautiful Nandana Sen, who once took offence to being called hot (she'd rather be known for her acting skills than her looks, she says), is in her mid-40s.

Yes, you read that right.

Before Indo-Canadian actress and model Lisa Ray got hitched to banking execitive Jason Dehni in October this year, she celebrated her 40th birthday in April.

With her fresh-faced look and flawless skin, she could give 20-something starlets a run for their money.

Former beauty queen Sangeeta Bijlani, who hasn't been seen in a film since 1995, is a Mumbai party circuit regular.

Do you remember the last time you met a 52-year-old woman who pulled off a figure-hugging top well?

We didn't until we saw this former actress in the picture above.

A force to be reckoned with in Bollywood today, the talented directed and scriptwriter Zoya Akhtar celebrated her 40th birthday this October.

Given her tiny frame and fiesty temperament, it's a little hard to believe she's 40, isn't it?

Tabu may have heavily cut down on work for now but the actress gives us a little something every now and then by way of public appearances.

Her minimalistic approach to fashion makes us love her even more but what's truly fascinating is that the actress is 41 years old and doesn't look a day over 30.

Model and Rockstar debutante Nargis Fakhri has such a striking and fresh face, you just assume that she's in her early 20s.

So it came as a bit of a shock that the former New Yorker is actually 33.

Malaika Arora Khan is one of the sexiest item girls in the film industry, even at 39.

Her hit Telugu item song from the film Gabbar Singh is proof that she's as popular down South as in Bollywood.

Former actress and jewellery designer Neelam Kothari is yet another Bollywood hottie, who's on the 'wrong side of the 40s.'

But considering the way she looks right now, she would just roll her eyes at that phrase and promptly move on.

If her career choices, crazy dimples and edgy haircut haven't given it away already, we'd like to say that Mandira Bedi is one sassy lady.

Wearing a Herve Ledger dress and totally owning it is a rare feat. More so if you are 40.

Another celebrity of the quirky kind, Sapna Bhavnani lives life on her own eccentric terms and is currently busy cooking up a storm in the Bigg Boss 6 house.

Her lifestyle clearly agrees with her. Hard as it may seem to believe, this boho-chick is now 41 years old.
