Tanner Buchanan has spent years playing one of television’s most reliably chaotic teenagers, but the plot twists he generates off-screen keep outpacing the script. The Cobra Kai actor went from training montages to an engagement with co-star Mary Mouser, then to a music-video kiss that fans still ask about. This is the fact-checked version of that story: what’s confirmed, what’s rumor, and which sources hold up.

Quick snapshot

1Confirmed facts
2What’s unclear
  • Exactly when Buchanan and Mouser became a couple — no source publishes a start date.
  • Whether his martial-arts rank means he competes — profiles list training, not tournaments.
  • Why Addison Rae unfollowed her mother in 2023 — no official explanation was issued.

4What’s next
  • The post-Cobra Kai career signal to watch is his next lead role.
  • No wedding date has been made public as of early 2025.
  • Fans keep searching “Mary Mouser and Tanner Buchanan married” — the answer remains “not yet.”

Six quick facts, one pattern: the databases agree on the basics, and the details get looser as they get more personal.

Bottom line: Buchanan is a confirmed actor with a verifiable engagement, but the timeline of his relationship and his martial-arts competition record remain undocumented.

The table below distills what sources consistently say about the actor.

Label Record
Born December 8, 1998 (IMDb profile)
Birthplace Lima, Ohio, USA
Known for Robby Keene in Cobra Kai; Leo Kirkman in Designated Survivor
Height 5′8″ / 1.73 m (Yahoo Topics); shorter estimates circulate (The Famous People, a celebrity biography database)
Relationship status Engaged to Mary Mouser

Did Mary Mouser and Tanner Buchanan get married?

Not yet — and the record is clear about it. Buchanan and Mouser, who play Robby Keene and Samantha LaRusso in Cobra Kai, became engaged, with the announcement dated to February 2025 (Wikipedia).

The marriage rumor probably grew out of the show’s ending: Robby and Sam end up together, and the actors’ real-life relationship followed. But the public timeline stops at “engaged.” No wedding date has been announced.

Why this matters

Search trends show fans asking “did Mary Mouser and Tanner Buchanan get married?” as if it were a settled fact. The public record says engagement, announced February 2025 — not marriage.

The pattern: on-screen romance plus a real-life engagement reads as a wedding to people scanning headlines. The gap between “engaged” and “married” is where the rumor lives.

Who is Tanner Buchanan’s ex-girlfriend?

The name that comes up most is Lizze Broadway, an actress whose credits include The Boys and American Pie Presents: Girls’ Rules. An older Capital FM profile listed her as Buchanan’s girlfriend (Capital FM, the U.K. pop-culture outlet).

Neither actor confirmed a serious relationship publicly, and no official statement has ever addressed it.

The trap

Old relationship data has a long shelf life. HealthyCeleb still lists Broadway as Buchanan’s girlfriend, years after mainstream profiles moved on to Mouser (HealthyCeleb, a fan-maintained bio database) — a good reminder to check the date on any celebrity bio.

The takeaway: one reported past relationship, zero official confirmations, and a long tail of recycled bios that never got the memo.

Is Tanner Buchanan a real martial artist?

He is a trained martial artist, not a competitive one. His on-screen fights in Cobra Kai came with real preparation — karate, taekwondo, and kung fu — and a fan-profile site calls him a taekwondo black belt (Coast Pulse). His broader martial arts in movies background is part of why the role reads as believable.

The curious origin: before any of that, Buchanan says he was a tap dancer, starting around age 5 (Cryptic Rock, a music and entertainment interview outlet).

The catch

A black belt is a training credential, not a fight record. No source documents Buchanan competing in martial arts, so the accurate phrase is “real training,” not “real fighter.”

The implication: he moves like a fighter because he prepared like one. Claiming more than that oversells the evidence.

Why did Tanner Buchanan kiss Addison Rae?

Because it was a job. The kiss appears in the official music video for Addison Rae‘s 2021 single “Obsessed,” where Buchanan plays her on-screen love interest (Wikipedia).

The scene took seconds to film and years to explain. Fans still treat the GIF as evidence of a real-life romance; the credit is a performance listed alongside his acting work.

The trade-off

That 30-second kiss bought Buchanan crossover attention well beyond Cobra Kai’s audience. It also handed the rumor mill a clip that still circulates as “proof” of a relationship.

The pattern: a scripted moment goes viral, and the context — music video, acting credit, storyline — rarely travels with it.

Who has Addison Rae dated?

The public record is thin and mostly tabloid-grade.

  • Bryce Hall — the influencer most widely described as her boyfriend around 2020–2021
  • Omer Fedi — music producer linked to Rae in 2023; never publicly confirmed
  • Single — the status most celebrity-news roundups used through early 2024

One thing she has addressed directly is anxiety; Rae has spoken about the mental-health toll of social media, though she has not published a formal diagnosis.

The honest answer: one confirmed public boyfriend, one unconfirmed link, and a default status of single. Everything else is “linked to,” not “dating.”

Where the Public Record Agrees — and Where It Doesn’t

Eight contested details, one pattern: the more a fact feeds a headline, the more versions of it circulate.

Detail What sources actually say
Height Most listings say 5′8″ (1.73 m); Capital FM’s older profile says roughly 5′7″ (Capital FM)
Martial-arts style Fan bios name taekwondo, karate, and kung fu; the exact style varies by source.
Early training Tap dance from about age 5, before any martial arts (Cryptic Rock)
Relationship record Some fan-run bios still list Lizze Broadway as his girlfriend, long after mainstream profiles moved on (HealthyCeleb)
Relationship start No public start date; profiles jump from co-stars to engaged.
Hometown Lima, Ohio is the common listing; Ottawa, Ohio appears in some references.
Age (early 2025) 26, consistent with the December 8, 1998 birth date.
Career span Cobra Kai’s run from 2018 to 2025 is the most consistent date range across sources.

The pattern: where a fact can be checked against a filmography or a database, sources agree; where a fact comes from interviews or social media, they drift. Trust the categories, not the copy.

Timeline: From Ohio to the Cobra Kai Finale

The signal: each milestone is publicly dated, but the most personal one — the engagement — is also the most recent, which is why the rumor mill is working overtime.

What’s Confirmed vs. What’s Still Unclear

Confirmed facts

  • He is an American actor (Coast Pulse)
  • He is engaged to Mary Mouser, announced February 2025
  • He trained in martial arts for screen roles

What’s still unclear

  • When the Mouser relationship actually began — no source publishes a start date.
  • Whether his black-belt training extends to competition — no source documents a fight record.
  • Why Addison Rae unfollowed her mother in 2023 — no official reason has been given.
  • Whether Addison Rae has a child — no reliable source confirms one.
  • Whether Addison Rae smokes — no credible report or photo record says so.
  • Whether Addison Rae has ADHD — no interview or report mentions it.

In Their Own Words

Two voices sum up the split in his public image: his own, and the database that tracks him.

“I was originally a tap dancer — I started tap dancing at about age 5.”

“Buchanan is best known for playing Robby Keene in Cobra Kai and Leo Kirkman in Designated Survivor.”

IMDb biography, the industry-standard film and TV database

For fans following Tanner Buchanan because of Cobra Kai, the practical move is to separate the public record from the comment-section version of it. The public record gives you a trained performer, an actor who got engaged in February 2025, and a music-video kiss that was always a performance. The comment-section version turns all of that into a wedding rumor with a timeline that doesn’t exist. Since the finale, the question is no longer what happens next on-screen — it’s whether fans will wait for the couple to announce their own next step, or keep inventing one.
