Teen Mom alum Jenelle Evans gave her eldest son, Jace, the sweetest shoutout on his 14th birthday.

The reality TV personality shared two new snaps of her and Jace posing outside on a deck, in front of a pond and pretty wooded area.

Her teen, now all grown up, nearly towered over her, wearing a sapphire polo shirt, khaki shorts and sneakers. Evans, now 31, was snapped in a nude tank top, silky orange midi skirt and platform Crocs. As for her glam, she let her natural glow shine through, wearing little to no makeup.

"14 YEARS OLD EVERYONE! 🎂✨" Evans exclaimed in the caption of the post shared to her Instagram grid on Wednesday, Aug. 2. "#HappyBirthday to Jace! You’re growing into a such polite young man. I’m happy as long as you’re happy! ❤️💯 @jace_vahn."

Fans of the MTV reality series couldn't believe how much time had passed since the family was first introduced to viewers or how grown up Jace looked.

This year's birthday celebrations are a big deal for the family as Evans only regained custody of her firstborn from her mom Barbara Evans about five months ago.

"ITS OFFICIAL!" the reality star wrote on TikTok March 18 alongside a video of her signing the paperwork and crying tears of joy. "Thanks everyone for the support! Words can't describe how happy I truly am. Our family is complete now! Thank you mom."

At the time, Evans told Us Weekly that she and her mom "decided together to grant full custody back to me because we want to build our relationship back as mother and daughter," she added, "Also, my mother agrees it's time for Jace to be back with his siblings and living with a mother and father."

This spring, Evans offered an update on her relationship with her son was "much better."

"My relationship with Jace is closer than ever and doing much better," she told E! News. "I feel like being with his family makes him much happier. Our family wasn't complete without him."

In addition to Jace, whom the former 16 & Pregnant star welcomed with ex Andrew Lewis, Evans is the mother to 9-year-old Kaiser Orion and 6-year-old Ensley Jolie. She shares her son Kaiser with her ex-boyfriend Nathan Griffith and her daughter Ensley with her husband, David Eason. Eason, whom Evans married in 2017, also has a daughter, Maryssa, from a previous relationship.
