Many of Netflix's Cobra Kai fans have shipped Mary Mouser and her co-star Tanner Buchanan in real life because of their onscreen chemistry. Nevertheless, 25-year-old Mouser has been in a committed relationship for six years, and she's not shy to share loving photos of her and her boyfriend actor Brett Pierce. Last December, Mary took to Instagram to celebrate their anniversary, writing, "Five years with you has felt like five minutes. Happy anniversary to the most spectacular boyfriend – who I am so grateful to say is also my best friend." Although Mary is happily partnered up, there's no denying that her onscreen love interest is pretty attractive. What about her co-star love life?

Tanner Buchanan is extremely private and doesn't reveal too much his love life on his Instagram account. Most of Tanner's fans probably know he's been in a relationship with his girlfriend, actress, and model Lizze Broadway for the long haul. Though it's unclear when exactly the two got together, Broadway recently told Anna Faris that they'd been together for six years already by the time she was 17, which means they really are childhood sweethearts. Although they briefly split as teens, they soon realized they didn't want to be apart.

Are Lizze Broadway and Tanner Buchanan Still Together?

Except for an Instagram post here and there, the couple tends to keep things private. As proof of it, the most "recent" post where Tanner mentions Lizze it's from four years ago. The actor wrote, "what do you do when the person you love comes to visit?" Other than that, the couple has been spotted at the 2019 Comic‑Con. They also have a shared YouTube channel, Lizze & Tanner, but rarely post on it. Being so private makes them susceptible to breakup rumors.

In 2021 fans started speculating that Tanner and his long-time girlfriend split up. This came after the couple seemingly deleted the few pictures they had together on Instagram. Of course, it didn't help that the actor and his He's All That co-star, Addison Rae, kissed on stage at The MTV Movie & TV Awards. Despite all the drama, it seems like Tanner and Lizze are still an item. In July 2021, Just Jared obtained photos of the two kissing on a balcony in Venice. The month after, Tanner called Lizze his girlfriend in a video for GQ.

The Kiss With Addison Rae That Briefly Destroyed Tanner Buchanan's Relationship With Lizze Broadway

The MTV Movie & TV Awards kicked off on May 16, 2021, and Addison Rae and her He's All That co-star, Tanner Buchanan, took the stage to present one of the award show's most iconic awards, aka Best Kiss. For a quick refresher, in past MTV Award years, this award goes out to one of the most memorable movie kisses, whether that be cringe-worthy or filled with intense passion.

Ryan Gosling and Rachel McAdams, who were dating at the time of the 2005 MTV Movie & TV Awards, recreated their infamous kiss from The Notebook, and viewers went wild. Since then, it's been a difficult task to live up to, and this time around, it seems Addison Rae and Tanner's mid-award-presenting makeout was met with some mixed reactions.

While presenting the award, which ultimately went to Chase Stokes and Madelyn Cline, the two made mention of the gender-flipped remake of She's All That called He's All That and attempted to prove to the audience that they knew a thing or two about a Best Kiss moment. The kiss immediately went viral as "Addison Rae" began trending on social media, which prompted speculation that she and Tanner were dating in real life.

Addison Rae's Ex, Bryce Hall, Reacted To Her Kiss With Tanner Buchanan

Others were not here for what they had just witnessed, like one person who tweeted, "I never ever wanna see Addison Rae kissing that Tanner guy ever again." Another person wrote, "Addison Rae really thought she did something by kissing Tanner, didn't she?" But perhaps the person who was most affected by the surprising PDA was Addison's ex-boyfriend Bryce Hall, who doesn't typically shy away from expressing his emotions via social media. The two split in March 2021 after rumors he had cheated on her during a trip to Vegas. However, he has since clarified that was not the reason behind their split.

Bryce took to Twitter as soon as he got wind of all the buzz, tweeting, "sucks, but moving on." It seems many fans would also like to move on from Addison and Tanner's kiss. On the other hand, although Tanner's girlfriend, Lizze Broadway, didn't make any public comments, fans think she must have felt betrayed and sad.

This isn't the first time Addison has received backlash while presenting during an award show. During the 2020 Billboard Music Awards, Addison angered Harry Styles fans after presenting him with the Billboard Music Chart Achievement Award and kind of completely forgetting to open the envelope and accepting the award on his behalf. It looks like practice makes perfect, and it's anyone's guess what Addison might do to surprise everyone the next time she takes on an awards show stage.
