MailOnline has an exclusive look at one of the cover girl's first photo sessions when she was only 15-years-old, long before she became the world's top pinup bikini model.

A new look at the beauty: Kate Upton in a photo shoot from when she was only 15-years-old; these never-seen-before images are a MailOnline exclusive

She had a glow: The Florida native sparkled in a silver minidress with neon yellow open-toe heels

She already had that signature charm: The natural beauty showed off her winning smile that has since landed her on dozens of magazine covers In a total of eight stunning sets taken by fashion photographer Steven Burton, the Florida native - who was born in Missouri - showed off her modeling skills as she folded her arms, pouted and smiled with enthusiasm. The photo session took place in March 2008, just after the teen was signed to Elite Model Management.

In one set the leggy looker showed off a fit figure in a shimmering silver mini dress. Bright neon open-toe yellow heels made a dramatic statement.

She wore no jewelry and overall had a natural appearance befitting a teenager.



With her hair in a loose updo and her makeup kept to a minimum, The Other Woman actress appeared more stripped-down than she has in her more recent shoots for Vanity Fair and Vogue.



Already the 5ft10in catwalker had glowing blonde highlights, but she had not yet evolved into a full-fledged blonde as she had some roots showing.

Another set sees her in a white button-down mini dress with a belt and pockets.

Her legs looked even thinner with opaque black stockings. Black heels elongated her frame.



Though the ensemble was a mish-mash of summer and winter looks, the GQ cover girl pulled it off effortlessly, with her natural charm saving the day as she smiled winningly at the camera.



Another set showed her in a sixties-inspired Bohemian look with a dark beige newsboy hat and a rainbow coloured sweater while low-cut black slacks with a wide white belt added to the hippie look.

Fresh faced: In the shoot, Upton wears minimal makeup, better showing off her natural beauty that includes strong arched eyebrows and full lips

An athletic background: Her mother Shelley Davis was a tennis champ in Texas

In this collection, Upton showed off her thick, dark eyebrows in a closeup. Though they were already groomed to perfection, they appeared heavier to how she wears them today. Her signature mole above her lip could also be seen.

Another black and white outfit - a flirty white skirt over the same black tights but this time with a black tank top - had a juvenile touch.

Kate made good use of a wicker-accented table as she both stood near it and sat on it with her knees curled up.

There's that signature smile: Even at age 15, Kate had that knockout grin that would help sell millions of bikinis one day

In a set-up taken outdoors in a wood-fenced backyard, the one-time flame of Maksim Chmerkovskiy put her hands on her hips while wearing a empire waist top with capped sleeves and cut out designs at the bottom.

Black slacks hid most of her figure, but it was apparent she was trimmer than she is these days with a tiny waistline and slender arms.



Kate showed off a more masculine side when she modeled a black pinstriped vest over a white button-down shirt with a black tie.

Future superstar: It was evident even from these early snaps that Upton had what it took to become a global sensation like Gisele Bundchen

With her hair parted in the middle and pulled back, she appeared to be more boyish, if that is even possible, and serious. At one point, however, the Tower Heist actress burst out into a broad smile, bringing life to the monochrome look. The star has put her success down to her girl-next-door image and curvaceous figure.

'I’m 21 and I love fashion and I feel like a normal girl – at least to a certain extent,' she tells The Talks in a new interview. 'I think that people can relate to me.

#katesureiscute: In the six years since the beauty took these shots, she has been on the covers of Sports Illustrated, Vogue, Elle, GQ and Cosmopolitan

Black and white and gorgeous all over: In this shot, Kate looks the most youthful as she poses with her arms crossed 'Most of the time the model is retouched and too skinny and other women get depressed by it. But really, that model who is being retouched and is too skinny is depressed as well because she doesn’t look like that photo either!

'It’s not realistic for that model or that woman reading the magazine to think she should look like that.' Although she now 'loves her body' and is 'confident where I am as a person', the model and actress revealed that was not always the case.

A rare look back: Though the sensation has been modeling professionally for over five years, there are not many photos from her early days as a mannequin

Still in school: At the time this shoot was done, Upton was attending the Holy Trinity Episcopal Academy

'At first it was terrible! she revealed. 'But then I got inspired by other women being inspired by me. Seeing that other women went through that as well made me stronger. 'I wanted to inspire them by going through it and making it out the other end. Everybody goes through hard times, regardless whether they didn’t get the job that they wanted or if they are being criticized for their body, so I think they can relate to that and people are rooting for me.

'Me being criticized is more on a global level, but it still hurts just as much for any girl if she’s at school being criticized or at work being criticized.'

Fresh like an autumn breeze: It's not hard to see why Guess made her their spokesperson in 2010, only two years after this photo was taken

Red alert: The teenager looked relaxed as she sat in a colorful room; at the time Kate was an avid equestrian and competed on a national level

A flair for comedy: She has already appeared in several films, including The Three Stooges and Tower Heist The star seems extremely aware of her public image and career path, telling the website that: 'I've always had in my mind where I should be at a certain stage.' For that reason, she has largely stayed away from being artfully photographed in a state of undress in a similar vein as models Kate Moss and Naomi Campbell.

'For me those photos are art,' says Kate. 'Your body is art, your body is beautiful, and to be photographed in that way is amazing and it's received in a very positive way. But with social media and the Internet and not so great blogs and the attention like that, I don't think that my pictures would be received in the way that I'd want them to be received. 'That's why I've stayed away from them. I really appreciate those photos and I think those women are beautiful, but I think social media and the Internet has prevented me from putting myself out there like that.'

She has famous friends: Upton is pals with Bachelor contestant Lucy Aragon as well as actress Cameron Diaz, her Other Woman co-star
