Are Mckenna Grace and Mason Thames really dating? While neither actor has confirmed a romance, fans can’t help but speculate after seeing their undeniable chemistry on and off the set of Regretting You.
The Handmaid’s Tale star, 19, and How to Train Your Dragon actor, 18, play love interests in the upcoming film adaptation of Colleen Hoover’s romance novel, which hits theaters on October 24, 2025. But their off-camera moments have sparked plenty of curiosity — and, yes, some racy TikTok videos have fueled rumors.
Fans first started speculating about a possible relationship back in April 2025 when a playful staged kiss between the two went viral on TikTok. Since then, the pair have been spotted spending time together outside of filming.
Although neither Grace nor Thames has outright confirmed a relationship, both have shared glimpses of their admiration for each other in interviews. Thames had plenty of praise for his co-star in a June 2025 Seventeen interview: “She is one of the most driven people I’ve ever met in my life. Every day I’m on set with her, I just want to be as good as Mckenna. She’s such a sweet person, and getting to do this movie with her is so cool.”
Grace, meanwhile, has remained playful when asked about their rumored romance. During an October 2025 interview on Today, host Jenna Bush Hager asked her, “So he’s your partner in the film, but is he also kind of your partner?” Grace burst out laughing, covering her face:
“What is happening?! It’s… I mean… I’m so sorry.” When prompted further, Grace kept her response coy: “No comment at this time… Yeah, we were in costume and in character there… I love Mason. He’s my favorite person.”
Their public moments, TikToks, and interviews have created a timeline of curiosity: playful on-set kisses in April, hand-holding in June, and continued teasing remarks in October. Fans continue to pour over every interaction, hoping for confirmation of what many hope is young Hollywood’s newest romance.
