The Bravo-lebrity took to Instagram on Wednesday to share a special video to celebrate daughter Brielle's 18th birthday -- and we couldn't help but notice how fresh-faced she looks in the early family photos.
"HAPPY 18th BIRTHDAY to my beautiful @briellebiermann Brielle you have taught me so much in these 18 years!" she wrote. "I'll never forget the moment I found out I was pregnant with you, I'll never forget the moment you were born, I was scared sh*tless I was a kid having a kid, You changed my life in an instant and I wouldn't have it any other way!"
"It was you and I for years just trying to make it, WE MADE IT HUNNI! I'm so incredibly proud of you, the woman you are becoming (you will always be my baby), you never cease to amaze me," she added. "You have made my job as your mom sooooo easy! I LOVE YOU ELLIE BELLIE BOO!!!!!! #IHopeYouNeverMoveOut #YouWereMyStrengthWhenIWasWeak."
In the pics, fans get to see candid moments between Kim and her daughter through the years, documenting big milestones and their changing looks.
The former "Real Housewives of Atlanta" star looks better than ever now, after giving birth to six kids -- check out her shockingly slim waist below!
The blonde bombshell has been criticized by haters who say her slim selfies are Photoshopped, but she claims it's the real deal.
While Kim admitted to getting a tummy tuck last year, she made it clear that she was in good shape before going under the knife.
"Just so you guys are aware of how fabulous I was before my tummy tuck ... A plastic surgeon is NOT the cure all," she said back in October. "I had a hernia I needed repaired as well as my muscles so don't get it twisted for you lazy asses that sit on the couch And think I look this good from a surgeon you are now set straight! enjoy!!"
Whatever she's doing ... it's working for her!
