Kim Zolciak is celebrating her daughter Brielle's 18th birthday with a fun file of retro photos. Here are a few of the great snaps (the text is edited lightly as you can see).

The "Real Housewives of Atlanta" alum, who actually goes by Kim Zolciak Biermann since marrying Atlanta Falcons player Kroy Biermann, is the happy (and busy!) mom of six now. Catch up with the gang when Bravo's "Don't Be Tardy" premieres July 17.

For now, Happy Birthday Brielle!

"HAPPY 18th BIRTHDAY to my beautiful Brielle you have taught me so much in these 18 years!!" Kim posted.

"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 (blank)less I was a kid having a kid."
