We could hardly believe it when Nene and Gregg Leakes' youngest son, Brentt, graduated from high school back in 2017. After all, when we met him on The Real Housewives of Atlanta in 2008, he was just a little boy of 9 years old. And the next thing we knew, Brentt was towering over his mom and dad. Well, time keeps marching on, and now the Atlanta son has officially wrapped his teenage years.

In a February 20 Instagram post, Nene shared intimate photos of her youngest child (she also has another son, Bryson.) The images captured Brentt as a baby and throughout his teenage years, and his mother penned a heartfelt birthday tribute:

"A king entered the world on this date after a full day of labor and changed my life forever! Brentt, mom and dad have loved you from the moment we saw those 2 faint blue lines on a home pregnancy test LOL! You are 20 years old today! No longer a teenager. Almost a full grown man making his way in this world (where the hell did time go)."

She continued: "As your mom, [I] want nothing but THE BEST for you. I’m praying you have the best year ever son! I pray you have a clearer vision for your life and future accomplishments! [You're] super funny and have an amazing personality (you probably got that part from me.) I’m proud of you and the young man you have become! The door is wide open baby....Walk thru it! Happy Birthday baby boy! Show my son some love y’all. He’s the best."
