Adam Levine has a racy new photo on Instagram. "The Voice" judge went shirtless and nearly naked in fiance, Behati Prinsloo's  cute photo, where the Maroon 5 singer only wore underwear.

According to US Weekly, the 24-year-old Victoria's Secret supermodel posted a candid image of her guy's hot body on Wednesday.

The crooner, 34, is almost nude in only black underwear, showing off his many tattoos. He also rocks dark shades, looking as if he just stripped off his clothes backstage at an event or concert.

Prinsloo captioned the hilarious photo, "70s porn called. It wants it's vibe back. Immediately."

The image has already won more than 20,000 likes on the site. It appears that the photo is a hit and favorite among Instagrammers everywhere.

One user, uniqcreations responded, " Good Gawd!!! LMAO!"

In July, Levine popped the question to his longtime love, Prinsloo.

"Adam Levine and his girlfriend Behati Prinsloo are excited to annouce they are engaged to be married," said Levine's rep to People in July. "The couple recently reunited and Adam proposed this weekend in Los Angeles." 

People reported that the couple began dating last year shortly after the Maroon 5 frontman split from well-known model, Anna Vyalitsyna. With the twosome anticipating a wedding, its pretty clear that they have reconcilated in a "big way."

And as they plan their wedding, Prinsloo is not shy about showing just a glimpse of sexy fiance to the world.
