Nothing but the bare essentials! Stunning supermodel Nina Agdal strips down to just a pair of sneakers for racy Sports Illustrated shoot 

Thanks to her multiple appearances in the Sports Illustrated Swimsuit Edition, we've all seen Nina Agdal's amazing body in a bikini - but newly-released photos show the Danish model like we've never seen her before.

Photographer Frederic Pinet shared a collection of unused test shots with SportsIllustrated.com's Swim Daily, and in some of them the 23-year-old stunner is wearing even less than the skimpy two-pieces she usually models. 

Clad in just a pair of athletic sneakers, Nina flaunts her figure and leaves nearly nothing to the imagination.

Nina is certainly no stranger to revealing skin, but these pictures may be her most revealing yet.

In other photos from the shoot, the European bombshell poses topless, wearing a sheer black bodysuit, and in a number of photos she is captured wearing nothing at all - not even those sneakers – with just a couple of carefully-placed black stars to protect her modesty. However, there are also uncensored versions of the photos available.

Last year, Nina posed topless - but turned to face away from the camera - on the cover of the 50th anniversary issue of the Sports Illustrated Swimsuit Edition, alongside Lily Aldridge and Chrissy Tiegen.

Though her body is certainly enviable, Nina has insisted that there is no secret to looking so svelte - and it doesn't happen by just sitting around, either.

'I [go to the] gym three to four times a week,' she told Elle last year. 'I like Barry's Bootcamp because of the intensity. I mix up my workouts to make sure I get cardio, toning, and strengthening covered. SLT and ChaiseFitness are great as well.'

But looking good in a photoshoot has a lot to do with swagger too, she explained to AskMen.com: 'You can't really fake confidence. You know what I mean? Just be confident in who you are when you walk into a room, feel like you own it.'

Though it might seem that way from a quick Google Image search of the star, Nina's life isn't actually all stripping down for photographers. The model also enjoys downtime with her boyfriend, fellow model Reid Heidenry.

Last month, the couple celebrated Nina's birthday with cake in the Lacoste Suite at the Miami Open, then watched the matches from the stands.

Earlier that week, they also got cozy in Miami Beach, sharing kisses poolside while they sipped on rosé wine in their swimsuits.
