Cobra Kai Stars Tanner Buchanan & Mary Mouser Are Engaged – It’s Official!
After years of fan speculation, Cobra Kai co-stars Tanner Buchanan and Mary Mouser have finally made things official—not only confirming their long-rumoured romance but also announcing their engagement in a heartfelt social media post.
The beloved duo, known for their on-screen chemistry as Robby Keene and Samantha LaRusso in Netflix’s hit Karate Kid spinoff, took to Instagram on Thursday with a joint post that sent their fans into a frenzy. The post featured candid snapshots of the couple walking through a hotel lobby, dressed elegantly for Cobra Kai‘s series finale event.
“We’re so happy to finally share that we’re engaged. This is such a special moment in our lives, the closing of one chapter and celebrating the continuation of another. We’re so grateful for the love and support, and though we’re partial to having our private moments, we’re excited to share this check-in to our world.” Buchanan wrote in the caption.
A Love Story That Had Fans Guessing for Years
For years, Cobra Kai enthusiasts speculated whether Tanner Buchanan, 26, and Mary Mouser, 28, were more than just close friends. While the pair frequently appeared in social media posts together and attended industry events side by side, they remained tight-lipped about any romantic involvement—until now.
Their engagement confirmation comes just one day after they turned heads on the red carpet at Cobra Kai’s Netflix event in Los Angeles, celebrating the upcoming release of the show’s highly anticipated sixth and final season. As they posed for photos, fans quickly noticed the silver rings adorning both of their hands—fueling immediate speculation before their official announcement.
Mary Mouser stunned in a shimmering brown mini-dress, paired with silver necklaces and bracelets, while Tanner Buchanan sported a sharp navy blue suit, complemented by a grey tie, a silver watch, and a pair of statement yellow sunglasses.
Tanner Buchanan & Mary Mouser – From On-Screen Romance to Real-Life Love
In Cobra Kai, Mouser plays Samantha LaRusso, the daughter of Daniel LaRusso (Ralph Macchio), while Buchanan portrays Robby Keene, the troubled son of Daniel’s longtime rival, Johnny Lawrence (William Zabka). The two characters had a brief romance during the show’s early seasons, leading to a love triangle that kept fans on their toes.
However, in real life, Tanner Buchanan and Mary Mouser maintained that their connection was purely platonic—at least, until now.
During a 2021 interview with Interview Magazine, Tanner Buchanan opened up about how filming romantic scenes with Mary Mouser felt unusual since they were simply friends at the time.
“The romantic scenes are what cause me the most anxiety,” he admitted. “You could talk to Mary about this because she and I are such good friends. When we had our first kiss scene in Season 2, they were asking us, ‘Are you ready?’ My heart was pounding, I was shaking. It just feels weird to go to that place because we’re such good friends.”
Clearly, that friendship blossomed into something much deeper over time.
Their Bond Beyond the Screen
Tanner Buchanan has often expressed how close-knit the Cobra Kai cast is, describing his co-stars as lifelong friends. Speaking with People at the Netflix event, he reiterated that Mary Mouser is “a hundred percent” his ride-or-die confidant but also emphasized his deep friendships with the entire cast.
“There’s not one person that we don’t hang out with and have fun with, and we truly keep saying that we’re going to be around in each other’s lives forever. I don’t know how to explain it.”
Their romance adds another layer to the already passionate Cobra Kai fanbase, which has closely followed the cast’s friendships and personal lives throughout the series’ six-season run.
A New Chapter Begins
Though they’ve kept their relationship private for years, Tanner Buchanan and Mary Mouser’s engagement marks a new era—both in their personal lives and in their journey as actors beyond Cobra Kai. While the show may be coming to an end, their love story is only just beginning.
As fans celebrate the long-awaited reveal, one thing is certain: the Cobra Kai community will continue to rally behind the couple, eager to see what comes next for them both on and off the screen.
Congratulations to Tanner Buchanan and Mary Mouser!
