Mary Mouser and Tanner Buchanan—who played Samantha LaRusso and Robby Keene on Netflix’s Cobra Kai—have announced they’re engaged.
The news followed the show’s series-finale premiere event in Los Angeles, where the pair sparked immediate buzz after appearing on the red carpet and showing off matching rings.
They confirmed the engagement in a joint Instagram post, calling it “such a special moment” and describing it as “the closing of one chapter and celebrating the continuation of another,” while also thanking fans for their support and noting they typically prefer privacy.

What it means for the stars and the show’s legacy
The announcement resonated with fans because the duo has long been linked off-screen, even as they avoided publicly labeling their relationship for years.
Entertainment Weekly noted that speculation had circulated for a long time, making their engagement reveal both a surprise and a confirmation of what many viewers suspected.
The timing also dovetails with a major transition for the franchise: Cobra Kai wrapped with its sixth season, closing the book on a series that began in 2018 and grew into one of Netflix’s signature crowd-pleasers.
