Charlotte McKinney and Joe Jonas strip off to reveal their incredible bodies for sexy new Guess underwear campaign

SLICKED-UP Joe Jonas and Charlotte McKinney set fans' hearts racing as they stripped to their underwear and pulled each other close in a very sexy photoshoot for fashion brand Guess.

The pair are very familiar with each other's bodies after getting raunchy in Joe's band's DNCE's Body moves music video last year.

Popstar Joe lashed on the oil and was seen cheekily pulling down Charlotte's trousers allowing the catwalk star to flash an extra peek at her toned bum.

Her muscly abs were on full display in her black crop as she pulled Joe's head closer towards her.

The former Jonas Brothers star went topless wearing just a pair of jeans, with the waistband of his designer boxers peeking from underneath.

Shortly after, Charlotte spun around to hold Joe from behind.

She flashed a sultry stare as she held his bare chest with one arm before peeking over his shoulder.

Another shot saw him show off his impressive six-pack and hunky pecks as he teased fans by exposing his underwear and pulling his trousers down.

Proceeding to rip them off completely, he perched on a chair in a pair of black boxers before deciding to lie back and, rather strangely, clutching a trombone.

After a swift outfit change, the American was then seen tearing off a grey top as he straddled a sofa.

Yet busty Charlotte made sure she also ramped up the sex appeal during their modelling campaign, as she showcased the collection's latest intimates launch.

Charlotte, 23, stripped to a sexy blue lace bikini with matching French knickers.

Her blonde hair fell over her shoulders as she twisted her body towards the cameras.

She later changed to a stunning cream and red bra which boosted her boobs and she drew yet more attention to her chest as she thrust her body forward.

Talking of the spring summer campaign, Joe said: "It feels great to be chosen by Paul Marciano as the male global ambassador for the new Guess Underwear campaign with a focus on the GUESS man.

"I am excited to be part of this amazing experience and to be able to represent the brand's image."

It seems DNCE singer Joe has a secret racy side.

We reported how the star, who The Sun exclusively revealed is dating Game of Thrones star Sophie Turner, revealed that his new band’s track Be Mean is inspired by his S&M experiments with his lovers.
