Everyone loves an intriguing showmance, and the press tour for “Regretting You” has fans buzzing about the off-screen chemistry between stars Mckenna Grace and Mason Thames. While it’s still unclear if they are officially dating, the duo’s flirty interactions have captured public attention, especially after Mckenna referred to Mason as her “favorite person” during a recent interview.
The timeline of their relationship began in August 2024 when the film adaptation of Colleen Hoover’s novel announced its cast, pairing Mckenna and Mason as lead characters. Their first public appearance together came shortly after, at Netflix’s Incoming House Party event, setting the stage for the intrigue that would follow.
Filming kicked off in March 2025 in Atlanta, and hints of romance began to surface in April when Mckenna shared a playful TikTok featuring a staged kiss with Mason. This online interaction had fans questioning the nature of their relationship further. The whispers intensified when the pair was spotted at an NBA game alongside their co-star, Dave Franco, and then again in May during a casual photo dump shared by Mckenna on Instagram.
By June, dating rumors gained momentum as they were seen holding hands in New York City. In a chat with Seventeen, Mason expressed admiration for Mckenna, referring to her as “driven” and “funny,” while acknowledging the unusual nature of having their relationship scrutinized.
In August 2025, Mason celebrated his birthday with Mckenna, describing their time together in Texas as “chill.” He praised her work ethic, a sentiment that has been echoed throughout their various public appearances and interviews. Mckenna kept the speculation alive with another cute TikTok, further tantalizing fans who are invested in their potential romance.
September brought more public outings for the duo, including a sweet moment during a “Regretting You” screening. The following month, when asked directly about their relationship during an appearance on “Today with Jenna & Friends,” Mckenna maintained a playful mystery by initially deflecting the question before affirming, “I love Mason. He’s my favorite person.”
As the press tour for “Regretting You” unfolds, fans are eager to see how this budding relationship between Mckenna Grace and Mason Thames develops, feeding into the excitement surrounding their film adaptation. The charming connection they share continues to captivate not only fans of the film but also those who enjoy the rollercoaster of celebrity romances.
