Cobra Kai stars Tanner Buchanan and Mary Mouser confirm relationship after years of speculation

Cobra Kai stars Tanner Buchanan and Mary Mouser just hard launched their relationship — and their engagement — following years of speculation from fans.

The longtime co-stars shared a joint post on Instagram on Thursday to announce their engagement. The post included pictures of Buchanan and Mouser walking through the lobby of a hotel, as they were dressed up for the series-finale event for Cobra Kai.

“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,” Buchanan wrote in the caption. “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

The news came after they walked the red carpet together on Wednesday during Netflix’s event for Cobra Kai, which is releasing the final part of its final (sixth) season on Thursday. As Mouser posed with her arm around Buchanan’s shoulder, they both held their hands up to reveal matching silver rings.

Mouser, 28, posed on the red carpet in a brown, sparkled mini-dress, along with a set of silver necklaces and bracelets. Meanwhile, Buchanan, 26, wore a navy blue suit and grey tie, along with a silver watch and yellow sunglasses.

During an interview with People at the event, the He’s All That star said Mouser was “a hundred percent” his ride-or-die confidant. However, he also acknowledged that he had close friendships with “literally everybody” in the Cobra Kai 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,” he said.

Buchanan and Mouser’s engagement comes as fans have questioned for years if they were together. While they’ve frequently posted about each other on social media in the past, they’ve never said they were an item.

In August 2021, Mouser shared multiple pictures on Instagram of her and Buchanan posing at an event for He’s All That.

“GO WATCH MY BEST FRIEND FREAKING KILL IT IN @hesallthatmovie!!! v v proud bestie right here,” she wrote. “Also - I love you, @tannerbuchananofficial, for putting up with my antics. And honestly, you usually just match my antics with your own, so thanks for that too.”

In Cobra Kai, Mouser plays a young karate star, Sam, the daughter of Ralph Machchio’s character, Daniel LaRusso, who he played in the original Karate Kid movies. Meanwhile, Buchanan plays Robby, the son of Daniel’s rival, Johnny Lawrence. During the show’s early seasons, Sam and Robby had a brief romance, which Buchanan previously discussed.

During a conversation with Interview Magazine in 2021, he shared how strange it was for his character to be in a relationship with Mouser since they were just friends in real life at the time.

“The romantic scenes are what cause me the most anxiety. You could talk to Mary [Mouser] about this because she and I are such good friends,” he explained. “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.”
