Hill is currently dating Sarah Brady. She's a community engagement leader for Changing Tides Foundation, according to The Sun. While it's unclear exactly when they started dating, the couple made their Instagram debut in September 2021 after Hill posted a loving picture praising his new girlfriend. "Grateful for you @sarahhbrady," the actor wrote in a since-deleted post (note: Hill deleted his IG altogether in August 2022 after revealing his struggles with anxiety, according to Page Six).
The two have mostly kept their relationship out of the spotlight, but that didn't stop engagement rumours from swirling in February 2022. People reported at the time that the rumours were unfounded, with Hill taking to Instagram to shut them down. The actor jokingly wrote, "The rumours are not true. I'm engaged. But not to my girlfriend. I am engaged to your mom. I know this is shocking but please respect our privacy at this time."
