Mckenna Grace and Mason Thames first met in July 2024, according to Thames, during an Uber ride to see Deadpool & Wolverine. He later told People that they clicked quickly and began spending time together regularly.

The pair were announced as romantic leads in the film adaptation of Colleen Hoover’s Regretting You in August 2024. They also began work on Nimrods, which started filming in February 2025, before Regretting You entered production in Atlanta the following month.

Their off-screen interactions drew attention in 2025. Grace shared a playful TikTok featuring a staged kiss in April, and the two were later seen together at an NBA game. In June, they were photographed holding hands in New York, prompting dating speculation. Thames told Seventeen that public interest in their relationship felt strange, while praising Grace’s drive and sense of humor.

Grace continued to share affectionate moments online, and the pair appeared together at a Regretting You screening in September. Asked about Thames during an October appearance on Today with Jenna & Friends, Grace initially declined to comment before saying, “I love Mason. He’s my favorite person.” Their film’s press tour brought further attention to their chemistry.

In February 2026, Thames posted photos of the two vacationing in Paris, including one in which Grace kissed him on the cheek. Grace commented that it was her favorite post “for unbiased reasons.” The following month, she brought him as her date to the 2026 Oscars.

They continued to celebrate milestones together, including Grace’s 20th birthday in June and Thames’s birthday in July. Nimrods reached theaters in August. Thames later described how they discovered they had signed on to two films together, saying the coincidence was unexpected and that working with Grace felt easy.

In September, Grace released the music video for her song “Bones and All,” which features Thames. In a November interview with Cosmopolitan, she called him her “best friend” and said she was happy to share her relationship publicly, while noting that some moments remain private for the couple.
