The story behind the abs has finally been revealed!

On Friday, September 16, Kim Kardashian took to Snapchat to show off her nude body after her midnight spray tan session, and now the star's go-to spray paint professional is revealing that the abs were also part of his work.

"While I was spray tanning Kim between layers as she likes to get dark she would go outside and took this snapchat while drying, have to admit spray tan looks pretty awesome on her and even painted her abs while spraying her," Fabiola Trujillo revealed on Facebook.

The 35-year-old star has never been shy when it comes to showing off her assets for the camera, but has been upping the nude selfie game after giving birth to son Saint West and documenting her drastic weight loss in the months that followed.

Now, the mom-of-two is not holding back when it comes to sharing her new look. Earlier this summer, she even teased a brand new nude photo shoot with fans.

“Have I posted a nude selfie since I lost all my baby weight?” the 35-year-old star teased. “I don’t think so. Get ready."

Looks like she's officially bringing them back!
