Kim Zolciak’s young sons are all grown up!

Taking to Instagram over the weekend, the “Real Housewives of Atlanta” alum, 46, shared a rare pic of KJ, 13, and Kash, 12, towering above her as they posed for pics at the Born to Compete Awards Gala.

The boys both wore all-black outfits for the event honoring their achievements in football, while their mom wowed in a metallic gown that featured a thigh-high slit on one side.

“I couldn’t be more proud of my boys @kjbiermann @ka.sh9330,” Zolciak captioned the snap. “Football is their true passion 😍They give it their all!! 🙏🏻🙏🏻 Early morning workouts, after school work outs, boats load of food, commitment, drive and a true love for the game. Makes me so happy ❤️.”

She cheekily added, “KJ is 13 and 6’1 🤩 Kash is 12 and 6’1🤩 (I’m 5’7 1/2 😜) 🙈.”

Zolciak’s former “RHOA” co-stars, along with hundreds of fans on social media, took to the comments section to point out how “big” the boys have gotten.

“OMGGGGG the boys are so big now! Growing fast 😍,” NeNe Leakes commented.

“Omg how time flies!!! ❤️❤️,” Shereé Whitfield added.

“Wow! Look at your boys! 😱 They are so big! And you look 🔥,” the “Real Housewives of Orange County” friend Gretchen Rossi chimed in.

Meanwhile, several fans also noted how the boys have turned into “handsome young men.”

The former couple, who have been going through a tumultuous divorce for nearly two years, also share 11-year-old twins: son Kane and daughter Kaia.
