Daniel is currently in a relationship with actress Erin Darke, who he crossed paths with while filming their 2013 movie, Kill Your Darlings.
"We met on the set...and just got on immediately. It was one of those instant things where you're like, 'Oh, I really like this person.' You just have a connection with somebody, and then suddenly it's incredibly easy to talk to them," Daniel said about their relationship in a 2014 interview with Parade. "It was one of those sort of situations."
