The 17-year-old actor has been winning hearts with his earnest performances, from The Black Phone to Incoming, and now he’s riding high on the success of this dragon-filled adventure.

But while his on-screen adventures are epic, many of you are curious about his off-screen life—specifically, who is Mason Thames dating? Let’s dive into what we know about Mason Thames’ relationship status, keeping things clear, honest, and friendly for all you young fans and entertainment enthusiasts out there.

Who is Mason Thames?

Mason Thames, born on July 10, 2007, in Phoenix, Arizona, is a young talent who’s quickly become a household name. At just 17, he’s already starred in major projects like The Black Phone (2021), where he played Finney, and Incoming (2024), where he charmed as Benj.

His latest role as Hiccup in How to Train Your Dragon has fans raving, with many praising his ability to bring vulnerability and heart to the Viking hero.

Is There a Girlfriend in Mason’s Life?

Mason Thames has not publicly confirmed having a girlfriend. The 17-year-old star, known for his captivating roles in How to Train Your Dragon, The Black Phone, and Incoming, is focusing on his booming career.

Rumors recently tied Mason to Nico Parker, his How to Train Your Dragon co-star. Their heartfelt portrayal of Hiccup and Astrid had fans wondering about off-screen sparks. In a June 2025 Seventeen interview, Mason described the cast as a close-knit family after filming in Ireland for nine months. Nico Parker addressed the buzz, confirming they’re just best friends with a strong bond from production. Their friendship is evident, but there’s no romantic connection.

Isabella Ferreira, who played Mason’s love interest, Bailey, in the 2024 Netflix comedy Incoming, also stirred speculation. Their on-screen romance and friendly vibe during 2024 promotional events caught attention, but sources report that they’re just good friends.

Mckenna Grace, Mason’s co-star in the upcoming Regretting You, faced similar rumors after a playful April 2025 TikTok highlighted their on-set chemistry. Fans online buzzed, some claiming they were dating, but Mckenna’s Good Morning America interview described Mason as a close friend and talented co-star. Their bond seems professional and friendly, not romantic.

Madeleine McGraw, Mason’s on-screen sister in The Black Phone, sparked chatter due to their frequent 2021 promotional appearances. Mason clarified in 2023 that they’re best friends, sharing a sibling-like dynamic with Madeleine’s sister, Violet McGraw, an actress.

A December 2024 article linked Mason to actress Lily Brooks O’Briant, suggesting they’re a couple supporting each other’s careers. However, without confirmation from Mason or Lily, and no recent sightings or social media backing, this remains unverified.

Mason himself stays quiet on the topic. In a 2024 TooFab interview, he shared high school experiences and called Incoming a fun teen adventure, but didn’t mention a girlfriend. During June 2025 How to Train Your Dragon press events, he shared anecdotes—like dressing as Hiccup for Halloween as a kid—but avoided dating talk.

Mason’s Focus: Career and Family

While fans are eager for girlfriend details, Mason seems more focused on his career and family. He’s got a packed schedule with projects like The Black Phone 2, set for release on October 17, 2025, where he’ll reprise his role as Finney, and New Years Rev, a Green Day-inspired comedy currently in production.

In New Years Rev, he plays one of three friends chasing a wild dream, alongside stars like Jenna Fischer and Angela Kinsey. These roles show his versatility, from horror to comedy to fantasy, and his dedication to his craft is clear.

Family is also a big part of Mason’s life. He has an older sister, Brooke Madison Thames, a talented ballet dancer who studies at the Colbourn Dance Academy in Los Angeles. The siblings are close, often spotted together at events like Universal Pictures’ Halloween party in 2022.

Their shared love for the arts—Brooke in dance, Mason in acting and former ballet training—keeps them grounded. Mason’s parents, Chad and Lisa Thames, have supported his career since he started acting at 11, moving the family to Los Angeles in 2018 to help him pursue his dreams.

Representation and Future Projects

For those wondering who’s guiding Mason’s skyrocketing career, he’s represented by top-tier talent agencies. While specific details about his current representation aren’t widely publicized, his work with major studios like Universal Pictures and Blumhouse suggests he’s backed by professionals who know how to handle young talent. His ability to land roles in high-profile projects like How to Train Your Dragon and Regretting You shows he’s got a solid team behind him.

Looking ahead, Mason’s slate is full of exciting projects. Monster Summer, released in 2024, showcased him in another leading role, and Regretting You, a Colleen Hoover adaptation, pairs him with Mckenna Grace in a heartfelt story about loss and love. These projects, along with his How to Train Your Dragon success, cement his status as one of Hollywood’s most promising young stars.

What’s Next for Mason?

As Mason continues to shine, fans can look forward to more of his work. The Black Phone 2 promises to bring back the chilling vibes, with Mason’s character Finney taking on a new role as a rescuer. New Years Rev will show off his comedic chops, and who knows what other projects he’ll tackle next? Whether he’s voicing Hiccup (he didn’t just voice him; he played him in live-action!) or taking on new characters, Mason’s future is bright.

If you’re eager for updates, keep an eye on credible entertainment sites or Mason’s own social media, where he occasionally shares glimpses of his life (mostly work-related, though!). And if you’re hoping for a peek into his heart, just know he’s keeping that part private for now—and that’s okay.

Conclusion

There’s no confirmed girlfriend in his life. Rumors about Nico Parker, Isabella Ferreira, Mckenna Grace, Madeleine McGraw, and Lily Brooks O’Briant have swirled, but none hold up without official word from Mason himself.

He’s single and focusing instead on his booming career and close-knit family. For young fans and entertainment lovers, Mason’s story is about a talented teen chasing his dreams and inspiring us all. Let’s keep cheering him on as he conquers Hollywood, one role at a time!
