Get ready for a good chuckle, Kim Zolciak fans. The former Real Housewife of Atlanta and current Don't Be Tardy... star recently took to Twitter to reminisce about the past when she posted a 20-year-old photo of herself to Instagram posing outside the NBC studios.

"Who would of thought I'd work for this network 20 yrs ago when this pic was taken!!" Kim wrote, along with the side-by-side photos of herself posing in the same spot today back in the day.

Her followers marveled at how much Kim, now 34, used to look like Brielle, while one fan even compared her to a young Julia Roberts.

But some more eagle-eyed fans raised their eyebrows at the idea that the girl in the original photo is only 14 or 15 years old. One person replied, "Kim it's time to fess up!! How old are you really? Because that does not look like a 15 year old back then sorry chica. Try a 22-24 year old."

Whoops!

Do you think Kim is lying about her age?
