The Timeline of Romance: 5 Definitive Clues They Are a Couple

The relationship between McKenna Grace and Mason Thames is one of the worst-kept secrets in Hollywood, with a clear timeline of events strongly suggesting they are more than just friends. Their connection began on the set of the upcoming film *Regretting You*, where they play on-screen love interests, but quickly blossomed off-camera.

1. The *Regretting You* On-Screen Chemistry

The initial spark and subsequent fan speculation can be traced directly to their work on the film adaptation of Colleen Hoover's popular novel, *Regretting You*. The pair star as young lovebirds, and their strong on-screen chemistry was immediately noted by the crew, the director, and, eventually, the public. This intense working relationship provided the foundation for their close bond, leading to the first round of dating rumors.

2. The Viral TikTok Kissing Video

Perhaps the most significant piece of evidence fueling the fire was a now-viral TikTok video that circulated widely across social media platforms. The video allegedly showed a moment where the two young actors shared a kiss, a moment that was viewed by fans as a definitive confirmation of their romantic involvement. While the context of the video and its official source remain ambiguous, the footage itself caused a massive stir, pushing the dating speculation into mainstream entertainment news. Mason Thames was later asked about the viral video in an interview, showing he was aware of the intense public scrutiny.

3. Intimate Public Outings and Red Carpet Moments

Throughout 2024 and 2025, the actors made numerous public appearances together that went beyond typical co-star promotional duties.

• First Public Appearance: In August 2024, Grace and Thames made their first notable public appearance together at Netflix's *Incoming* House Party event.
• Hand-Holding in NYC: A key moment was a casual outing in New York City where the pair were photographed holding hands. Hand-holding is a classic signifier of a romantic relationship, especially when the two are not actively promoting a project.
• Concert Dates: They were spotted attending major music events together, including a Green Day show in September 2024 and a Taylor Swift concert, further suggesting they share personal time outside of work.

4. The Flustered Response to Relationship Questions

While neither has formally announced their relationship, their reactions when directly asked about the rumors speak volumes. McKenna Grace, in particular, was noted to have struggled to maintain her composure and appeared flustered when asked about her relationship status with Mason Thames during an appearance on *Today with Jenna & Friends*. Similarly, Mason Thames addressed the speculation in an interview promoting his film *How to Train Your Dragon*, acknowledging the public interest without giving a definitive "yes" or "no". This pattern of being unable to fully deny the romance is often interpreted by fans and media as a tacit confirmation.

5. The "Still Together" Update of Late 2025

The most recent reports, even as late as October 2025, indicate that the two are "still together," suggesting their romance is not a fleeting rumor but a sustained, low-key relationship. This commitment to supporting each other's projects, attending events together, and maintaining a close bond over an extended period—well over a year since their first public outing—serves as the strongest evidence that McKenna Grace and Mason Thames are, for all intents and purposes, a confirmed couple.

Why The Relationship Has Resonated With Fans

The intense public interest in the McKenna Grace and Mason Thames relationship is a phenomenon driven by several factors, making them one of the most talked-about young couples in the industry.

The Power of Young Hollywood Romance

Both actors represent the new guard of Hollywood talent. McKenna Grace has successfully transitioned from a celebrated child star to a versatile actress and musician, while Mason Thames has quickly become a sought-after leading man after his performance in *The Black Phone*. Their combined star power and the narrative of two talented, successful young people finding love on a movie set is a classic Hollywood storyline that fans adore. The pairing feels fresh, authentic, and naturally derived from their professional collaboration on *Regretting You*.

Keeping It Private in the Social Media Age

In an era where every moment of a celebrity's life is often shared, the couple's decision to keep their relationship "refreshingly low-key" has only increased the public's fascination. They have successfully navigated the intense scrutiny of social media, including viral TikToks and fan speculation, by maintaining a level of privacy. This measured approach makes the occasional public sighting—like holding hands in New York or attending a concert—feel like a rare, special glimpse into their genuine connection, rather than a publicity stunt. The combination of strong evidence and a lack of a formal statement creates a compelling, ongoing mystery that keeps them in the news cycle.

Topical Authority and Key Entities

The narrative of their relationship is deeply intertwined with their professional lives, creating a rich tapestry of topical authority. Mentions of *Ghostbusters*, *The Black Phone*, *How to Train Your Dragon*, *The Handmaid's Tale*, and the highly anticipated *Regretting You* all serve as relevant entities that connect their personal lives to their professional success. This cross-pollination of career highlights and personal milestones ensures that any discussion of one inevitably leads to the other. In the eyes of their fans, they are a package deal—two rising stars supporting each other's journey to the top of the entertainment world.
