Padma Lakshmi fans could not believe how old she was as she sizzled in a new Instagram post from Monday.

'How old is this chick because she looks 35,' remarked one fan while another commented: 'No way she is over 40!' 

The leggy looker appeared very slender and toned as she made the most of a hot pink bikini.

The chef was enjoying a day at the beach as she walked along the shore alone during an impromptu photo session on her 55th birthday.

The former Vogue fashion model let her black hair down as she wore a gold necklace with charms while talking about writing her eighth book and coming out with a new TV show.

The star was taking in the last of summer on Labor Day in The Hamptons, which is not far from New York City.

And the reality TV star also left a long caption: 'I’m so grateful for this last year around the sun. It’s been productive professionally and also very moving to watch #Littlehands start high school and continue to blossom. 

'I’m so grateful that all of you have joined and supported me on this roller-coaster ride.

'Two years ago, I took a leap, and there was so much that was unknown. Would I work again? What would the future bring? I’ve been pivoting and plotting the next phase of my life—and it’s here now. 

'As I celebrate this birthday, I’m so thankful I’m about to create a new show, all my own, with amazing people around me working hard to bring you something that’s entertaining, engaging, and informative. And I’m also about to publish my 8th book.

'So this coming year will be full of blessings too. I couldn’t have done any of this without you all cheering me on. Thank you, and happy birthday to me!;

She is best known for hosting Bravo's Top Chef from 2006 until 2023. Lakshmi has also hosted the Italian program Dominica In.

This comes after she talked about her changing body when launching her Padma X Bare Necessities line last year.

'I know that women’s bodies change and have different needs,' said the former Vogue cover girl.

'I hope this collection makes you not only look good but feel good,' she noted. 'I hope that my selection is versatile and makes women feel not only like they have something pretty and special on, but that it’s functional.'

Her body has changed in recent years as she has gone from a 34C bra size to a 36DD. And she has also said her hips got wider.

Now she wants to serve 'a variety of customers' of all body types.

'I’ve always wanted to do a lingerie line,' the TV star - who talked about her 'sexual peak' recently - shared.

And she wants voluptuous women to feel safe. 'I hope that everybody enjoys the lingerie, but I designed it for women who might be a little more well-endowed,' she noted.

The ex of author Salman Rushdie has embraced the changes to her body since she crossed 50.

'As I have aged, I’ve found that my breasts have gotten bigger, and if you have a bigger bust, often you don’t get enough coverage,' the Taste The Nation star added.

The star noted that she recently went from a 34C bra size to 36DD, which she said she 'wasn't prepared for.' 

'So, I wanted something that would look pretty, but give the support that a woman with a larger bust needs, without looking matronly. We also have things like a beautiful bikini that look great on women with smaller busts.'

Turns out there is more of Padma to love. 

'As I’ve aged, I’ve needed more support; my breasts have gotten bigger, and my hips have gotten curvier,' said the siren.

'And I prize comfort more than I used to. When I was young, I didn’t mind wearing uncomfortable things to look good, but now I’m not willing to do that as easily. '

The lingerie has 'rich textures, intricate prints and mix of influences she’s gathered across the globe,' said a press release.

There are supportive bras and swimsuits as well as loungewear and coverups.

'I think putting on a nice piece of lingerie can be a mood-lifter,' she also said.

'Even if you’re in jeans and a T-shirt, it can make you feel dressed up on the inside. 

'Wearing lingerie is a way of caring for yourself that’s very private, and that’s also what I love about it. It’s just for you, and those you wish to share it with, of course.'

The line is more than bras, however. 

'I wanted to try my hand at a few different garments, and these items seemed like a good place to start. It’s a humble capsule offering of the things that I think every woman needs: a couple of bathing suits, a bodysuit, a corset, bras, some pants to lounge in, a coverup to throw on over said bra and a stretchy, long dress to hang out in that’s cozy but shapely.

'Pretty, delicate sky blue lace makes for a heavenly matched bra and panty set.

One of Padma’s personal favorite pieces is this zip-up rashguard.

'One of my favorite pieces is the zip-up rashguard with the mesh panels. When you’re going to the beach, you have to put on sunblock, but it’s such a pain, especially if you’re a mom or you have a lot to do. This bathing suit is one-piece, with long sleeves for more coverage. 

'It’s a very utilitarian suit that also looks sporty, sexy and chic in a Bond Girl way, but without being too revealing. If you wanted to be more modest, it would be a good thing to wear. 

And she kept the American woman in mind when designing. 

'I don’t pretend that my tastes are always mainstream, so it was important for me not only to design for myself but for other women, too,' said Padma.
