The video, which shows the duo singing together with Grace accompanying on acoustic guitar, features a cheerful backdrop with a “Happy Birthday” sign, enhancing the celebratory vibe.
The video quickly gained traction on the platform, amassing over 740,000 likes and approximately 4,500 comments within mere hours of being posted. It seems that the young fans of both actors eagerly embraced the charming display of friendship and talent. Prior to this heartfelt posting, Grace had not shared any content from her TikTok since June 10 and had also been busy promoting their upcoming film collaboration, “Nimrods.”
On Instagram, Grace continued the birthday festivities by sharing a candid snapshot of Thames in a vehicle, captioned, “happy birthday to my best friend 🤎.” The pair’s friendship has generated considerable attention, especially following their on-screen chemistry in the film “Regretting You,” where they portrayed a teenage couple.
The two young stars have established themselves in Hollywood over the past year. Their previous project, “Regretting You,” is an adaptation of the popular novel by Colleen Hoover. Following this success, they will reunite on screen in “Nimrods,” which is set to hit theatres on August 14 and is inspired by the iconic band Green Day.
Grace recently celebrated her own milestone birthday, turning 20 on June 25, and not long after, shared moments from her celebration, including a whimsical image of Thames and a sea lion, and another shot of him presenting her with flowers. Thames commented on her post, expressing disbelief at her turning 20, stating, “I can’t fathom she’s 20 🥹,” demonstrating a close bond between the two.
The rapport and camaraderie shared by Grace and Thames have sparked speculation about a potential romantic relationship, especially during their promotional tours for “Regretting You.” Their interactions on social media have led fans to hope for a budding romance, although both have been careful in how they express their feelings publicly.
At a special screening for “Regretting You” in October 2025, Thames spoke about the thoughtful birthday gift he received from Grace for his 18th birthday the previous July, which included a Spider-Man-themed wallet and backpack. He noted his aspiration to portray Spider-Man in the future, citing “Spider-Man 2” from 2004 as his favourite film in the franchise.
The burgeoning friendship and professional partnership of Mckenna Grace and Mason Thames serve as a refreshing narrative in a busy entertainment landscape. Their upcoming projects, combined with their supportive presence on social media, suggest that the duo’s star is only set to rise in the coming years. As the pair continue to navigate their teenage years in the public eye, fans are keen to see what the future holds for both of these talented young actors.
