Phillip Faraone // Getty Images Fact of life: Everyone loves a good showmance, which is why the Regretting You press tour had the internet positively spiraling. For months, the film’s stars Mckenna Grace and Mason Thames teased fans about whether or not they were dating in real life with their flirty off-screen behavior…until, at long last, they officially hard-launched their relationship.
And by hard-launched, I mean Mckenna brought Mason as her date to the biggest night in Hollywood, the 2026 Oscars.
The couple was back on our screens with Nimrods , and Mckenna’s next flick, The Hunger Games: Sunrise on the Reaping , is dropping any day now. Which means the time has come to review Mckenna and Mason’s relationship timeline from the very beginning. Starting with...
According to Mason, he and Mckenna first meet in the back of an Uber to see Deadpool & Wolverine in theaters.
“From the moment I met her, we were in this Uber going to see, I think, Deadpool & Wolverine ,” he later tells People in October 2025. “And instead of it just being super, super-duper awkward for a first meeting, it was so funny and so awesome.”
He adds, “We just clicked immediately, and ever since then, we just hung out all the time.”
The cast for Regretting You —the film adaptation of Colleen Hoover’s novel of the same name—is announced, with Mckenna and Mason set to star as the film’s romantic leads.
Soon after, the two make their first public appearance together at Netflix’s Incoming House Party event.
Mckenna drops a sweet video with Mason at a Green Day concert. Perhaps it’s prep for their first movie together, Nimrods …
Believe it or not, Nimrods (previously named New Year’s Rev ) started filming before Regretting You in February 2025, making it Mason and Mckenna’s first movie together!
Filming begins in Atlanta...and presumably, sparks start flying.
Mckenna oh-so-casually drops this TikTok of a playfully staged kiss between herself and Mason, which has fans like ??????

In May, Mckenna posts a photo dump on IG, which includes a few cute candid pics of herself and Mason. Swiiiipe:
Mckenna and Mason first spark dating rumors after they’re photographed holding hands while spending time together in New York City. I mean...
Later, Mason chats with Seventeen and has nothing but good things to say about Mckenna, calling her “one of the most driven people I’ve ever met in my life” and “one of the funniest people I’ve ever met.”
When asked how it feels to have so many people speculating about their relationship (particularly after *that* TikTok), he says, “Yeah, it is strange. But I’ve always sort of been off the internet. I’ve always kind of kept everything to myself and been very personal. Having people speculate so much, especially having mutual friends texting me and asking…it’s wild. I’m still not used to it.”
Mason celebrates his birthday...with Grace! As he explains to People , “I was home back in Texas and I got like a little birthday week and Mckenna was also there, and that was really nice. We spent that together and I spent some time with my family and some of my best friends, and it was nice. It was chill.”
Of Mckenna, he adds, “She’s so funny and such a nice person, so she gels with everybody.” Asked about their experience filming together, he continues to gush, “I've never met somebody with a work ethic like hers. She pushes herself every day harder and harder and she’s so incredibly talented. So just watching that, it really motivates me.”
Plus, Mckenna keeps relationship rumors alive with this cute TikTok:
The two stars attend a screening for Regretting You and have lots of sweet moments, like this one. Ahem:
Mckenna is asked about that April TikTok during an appearance on Today with Jenna & Friends , with Jenna Bush Hager straight-up saying, “So he’s your partner in the film, but is he also kind of your partner?”
And while she initially dodges the question with a “no comment,” Mckenna eventually says, “I love Mason. He’s my favorite person.”
Plus, the Regretting You press tour begins, leading to plenty of moments like these:
After nearly a year of dating rumors, Mason takes to Instagram to share pics of himself and Mckenna vacationing in Paris—including one photo where Mckenna is kissing him on the cheek in front of the Eiffel Tower.
Mckenna then slides into the comments section to write , “this is my favorite post.. for unbiased reasons.” Ooh-là-là!
In case you have any doubts left about Mckenna and Mason’s relationship status, she fully brings him as her date to the 2026 Oscars, where they share lots of cute moments like this one:
Also! Here’s some fun BTS moments from Mckenna:

Nimrods hits theaters, giving us even more of these two together on the big screen.
Mason also chats with E! News and reveals how he and Mckenna first found out they were doing back-to-back movies together.
“I was filming How to Train Your Dragon 1 and I had signed on to Green Day maybe a couple of weeks before,” he recalled. “I didn’t think she was signed on. It wasn’t even a thought in my mind. Then I signed on to Regretting You with Mckenna. I’d met her once before, so I texted her and I was like, ‘Hey, super excited to work with you. It’s gonna be fun.’”
He continued, “She was like, ‘Yeah, I’m so excited for Green Day.’ I was like, ‘What? What are you talking about? Green Day?’ So we found out we were doing two movies back-to-back. It was a wild, crazy, weird coincidence.”
Oh, and he also says this of his connection with Mckenna: “We say all the time, if we hadn’t met before, and we met on the day and were shooting a movie, our chemistry would be the same. That just goes with how easy it is to work with her.”
Mckenna drops the music video for her new song “Bones and All”—and surprise! It stars her real-life BF.
During her Cosmo cover story interview (hi!), Mckenna gushes about her connection with Mason, whom she refers to as her “best friend.”
“Your girl is happy,” she says of her love life. “I’m feeling very lovey-dovey. I have somebody I can be a complete nerd with. I got my best friend, and so I don’t see the point in not loving loudly.”
She adds, “There are moments that are just for you and your person. But I don’t see the point in not celebrating who you’re in love with. A lot of people’s hesitation around this stems from the idea that if you post about someone a bunch and then you break up, that’s embarrassing. But why would I even think about that? I’m just going to focus on the present.”
And she concludes with, “I am the biggest fan of the person I’m with, so why wouldn’t I be like, ‘This is my person. I am so stoked I have this’?” The cutest!
