Cynthia Bailey's little girl, Noelle Robinson, isn't so little anymore. The Real Housewives of Atlanta teen is officially 17, and her mom can hardly believe how much time has passed since she welcomed her daughter into the world. "Thank you [Leon Robinson]," Cynthia wrote to Noelle's dad. "Our daughter @noellerobinson is 17 years old today. Can u believe it? We did that."

Cynthia was feeling all sorts of nostalgic and whimsical as she reflected on being Noelle's proud mama. "Being your mother is an honor and a privilege. Continue to be courageous, kind & loving. Follow your dreams my dear. Life is precious, and you only get one. Live it to the fullest. Happy Birthday Beautiful. I love you beyond,' she shared.

In addition to all the warm wishes and reflections, Cynthia also posted an incredible photo of Noelle as a Barbie doll which is giving us all sorts of *NSYNC vibes.

HBD, Noelle!
