Thames and ‘Regretting You’ co-star McKenna Grace went Instagram official with their relationship after speculation
Mason Thames has confirmed his relationship with Regretting You co-star McKenna Grace after sharing photographs of the pair celebrating Valentine’s Day in Paris.
The actor posted a series of images on Instagram documenting their trip to the French capital, including café visits and walks through the city.
One image in particular drew significant attention, showing Grace kissing Thames in front of the illuminated Eiffel Tower. The post effectively confirmed months of speculation about their relationship.
Dating rumours surrounding the young actors began in April 2025 while they were filming the adaptation of Colleen Hoover’s novel Regretting You. At the time, some observers suggested their apparent closeness was a publicity strategy linked to the film’s promotion.
The pair were also seen holding hands in SoHo and celebrating Thames’s 18th birthday together in Texas. Their frequent appearances on each other’s social media accounts also led fans to question whether the relationship extended beyond publicity.
Regretting You, released in October 2025, centres on Clara Morgan, played by Grace, and her love interest Miller Adams, portrayed by Thames. Their on-screen chemistry was widely noted following the film’s debut.
