Twenty-one candles. That is how many Alex Johnston blows out today — Sunday, November 15, 2026 — exactly two days before 7 Little Johnstons returns for Season 18 on Tuesday night. The shy kid who once let his siblings do all the talking is now 21, with a promise ring given and an engagement planned for next year. Here is how he got here, date by date.
November 15, 2005: A Baby Boy From Seoul
Alex Johnston was born in Seoul, South Korea, on November 15, 2005. A month later, in December 2005, Trent and Amber Johnston got the phone call every adoptive parent waits for: there was a baby boy from South Korea who needed a home. Alex became the youngest of their five children — Jonah, Elizabeth, Anna, Alex and Emma — all of whom share achondroplasia, the form of dwarfism the family has lived with on camera for more than a decade.
2015: The Shy Kid the Cameras Found
When 7 Little Johnstons premiered on March 31, 2015, Alex was nine years old — the quiet one, the kid who let his siblings do the talking. The early years were not all easy television. In 2015, Alex stopped breathing during a routine MRI, a health scare that shook the family, and a brain surgery followed while he was still a kid. He came through both, and the shy boy slowly started finding his voice on screen.
2022 to 2024: Allie, Prom, and a Diploma
Everything changed when Allie Smith came into the picture. Alex has been in a relationship with Allie since 2022, according to reports, and the two attended prom together in Season 14. His 18th birthday, on November 15, 2023, got the full Johnston treatment — a Top Gun-style celebration with friends, and Allie flying in to join the party. Newly 18, Alex registered to vote and bought his first lottery tickets. Then, in 2024, he graduated high school alongside Emma, closing the school chapter that had defined most of his on-screen life.
The Christmas Box: A Promise Ring, Not a Proposal
The moment that turned Alex from the quiet kid into the Johnston with the clearest plan came in a Christmas gift box. His sister Emma went with him to pick out the ring — and talked him out of anything flashy, because she knows Allie’s style better than he does. Then, on camera, Alex told his family what was inside the box: her favorite perfume set — and the promise ring he gave Allie.
The contrast with his older brother could not be sharper. Jonah has been with his girlfriend Ashley for seven years and still has not given her a promise ring — and, according to reports, Ashley wants the real thing, not just a promise. Jonah’s own timeline from NICU baby to 25 is a story of waiting; Alex’s is a story of moving.

This fall, Allie did something none of the other partners managed: she earned a headline with nothing to do with a Johnston boy. On October 24, 2026, she received the American FFA Degree, a top honor in the youth agriculture organization, and the whole Johnston family publicly celebrated her. It matters for what comes next, because the farm at the center of Alex’s plan is hers.
November 15, 2026: Twenty-One Today — and Tuesday, the Plan
So here is where the timeline lands: Alex Johnston turns 21 today, and on Tuesday, November 17, at 9 p.m. ET/PT, Season 18 premieres on TLC with his next chapter front and center. According to reports, Alex hopes to get engaged to Allie next year and eventually move to her family’s farm to work there. The obstacles are real — Allie’s parents have reportedly ruled out moving in together before marriage, and the wedding race with his older brother Jonah hangs over everything, because Jonah has said his little brother should not marry first.
Twenty-one years ago, a baby boy from Seoul arrived in Forsyth, Georgia. Today he blows out 21 candles with a ring already given and a proposal openly planned.
So, on Alex’s 21st birthday, who should walk down the aisle first — Alex, who already has the ring and the plan, or Jonah, who has seven years with Ashley and still no ring? Team Alex First, or Team Jonah First?
