A Long-Term Love That Quietly Ended

Before fans began speculating about a romance with Cobra Kai co-star Tanner Buchanan, Mary had been in a long-term relationship with actor Brett Pierce. They started dating in 2015, and for over five years, they appeared together at events, posted birthday tributes, and supported one another.

Their relationship, though public in moments, was never overexposed. In December 2020, they celebrated their fifth anniversary, a milestone that fans cherished. However, the pair later parted ways quietly, with no dramatic announcements or social media statements. The breakup, while unconfirmed officially, became apparent as they stopped appearing together and removed older couple posts. It was a mature, respectful ending that reflected Mary’s private nature.

Sparks on the Set of Cobra Kai

Mary Mouser met Tanner Buchanan on the set of Cobra Kai, where their characters, Samantha and Robby, had a brief romantic storyline. Their chemistry was undeniable on screen. Off-screen, fans began noticing subtle signs that the actors may be more than just co-stars.

They were often spotted goofing around during interviews, attending conventions together, and even visiting Disneyland in casual friend groups. But it wasn’t until the Cobra Kai series finale in February 2025 that things became official.

The Red Carpet Reveal

At the final Cobra Kai event on February 12, 2025, Mary and Tanner walked the red carpet together—and this time, they weren’t just colleagues. Both were wearing matching rings on their ring fingers. When asked about the rings, they smiled coyly and later confirmed their engagement in a joint statement.

The reveal came as a delightful surprise to fans. Their moment was warm, not overhyped, filled with smiles and affection. It was a fitting way to mark the end of the show that brought them together and the beginning of a new personal chapter.

From Private Glimpses to Public Joy

Even before the engagement, fans had speculated about their connection. They often posted pictures with each other on Instagram, shared heartfelt birthday wishes, and were seen together outside of promotional events. But Mary never confirmed anything until she was ready. This slow reveal has made the relationship feel genuine, a refreshing contrast to the whirlwind Hollywood romances that often burn out quickly.

Now that they’ve gone public, they’ve received overwhelming support from fans and media alike. Tweets and comments poured in celebrating the couple, noting how their bond had always felt real—even when it was behind closed doors.
