Behold, Kim Zolciak-Biermann's most honest Instagram post to date -- One that involves her going au naturel.

The typically glammed up reality star took to social media on Dec. 14 to show off her fresh, makeup-less face, and she still looks good!

"Thank you Magnolia Spa for my amazing Hydra facial today!" she captioned the smiling snap. "No they didn't ask me to post, no I didn't get paid to say this! It's the only spa me and my entire family go to here in GA! They are the best! #PrettySkin #Maintenance #MaybeShesBornWithIt."

In the image, Kim's hair appeared to be tended to, but her skin looks as clear as can be, with a slight shine appearing on her forehead (something makeup could easily get rid of.)

Kim's face has been a source of controversy for some time, with many believing she has had work done on her moneymaker, something she has denied.

In August on "Watch What Happens Live," a caller asked Kim if she had work done to enhance her beauty. Kim rolled her eyes during the question, quickly saying, "No. I hear you, and I hear this all the time, but I want people to understand. I had a baby in 2011, one in '12 and two in 2013. So I think the weight of all that...but I mean, no, I haven't."

Kim has admitted to getting Botox and having surgery on her breasts and stomach.

"I'm very honest with plastic surgery," she said. "I've never hid anything, we all know that I do Botox and I'm a big fan of it. My lips are definitely over-drawn."
