The pair were first spotted spending time together in Santa Barbara in September 2022. The Oscar-nominated actor was previously engaged to Gianna Santos before calling it quits in October 2020. Hill was then linked to surfer Sarah Brady and shut down claims that the two were engaged in February 2022. Andrew Toth/Getty Hill — who has become increasingly private in recent years — revealed in an open letter to fans that he has long dealt with anxiety and panic attacks and explained why he would not promote his documentary Stutz in the summer of 2022. "The whole purpose of making this film is to give therapy and the tools I've learned in therapy to a wide audience for private use through an entertaining film," Hill wrote in August, per Rolling Stone. "Through this journey of self-discovery within the film, I have come to the understanding that I have spent nearly 20 years experiencing anxiety attacks, which are exacerbated by media appearances and public-facing events." While the 21 Jump Street alum wrote that he understands he is part of "the privileged few who can afford to take time off" and that he "won't lose my job while working on my anxiety," he hopes that being transparent about his anxiety will "make it more normal for people to talk and act on this stuff," so "they can take steps towards feeling better and so that the people in their lives might understand their issues more clearly." "I hope the work will speak for itself, and I'm grateful to my collaborators, my business partners, and to all reading this for your understanding and support," Hill concluded.
