The actor likes to remain mum when it comes to his personal relationships. Though he has been linked in the past to his previous co-stars such as his 5th Wave co-star Chloë Grace Moretz and his Melissa & Joey co-star Taylor Spreitler, these relationships have never been confirmed.

Additionally, Nick is not very active on social media. If you follow the hunk on Instagram, you'll see that he rarely posts pictures. But, when he does grace fans with his presence on the social media platform, it's usually snaps of his work, or most recently a montage of his time working on Netflix's Maid.

While it's safe to assume Nick is not going to dish on who he is dating anytime soon, the actor referenced his girlfriend in a November 2020 interview with InStyle.

When asked by the interviewer to say a joke, Nick replied, "My girlfriend told me this actually."

During a November 2020 interview with Variety, Nick also gave a small anecdote about his mysterious girlfriend, revealing that the two tested positive for the coronavirus (also known as COVID-19).

"My girlfriend and I both actually caught COVID in New York in March. We both got sick," he told the outlet. "Luckily it was very mild. We had some fevers and we lost our senses of taste and smell. But after that we had tested positive for antibodies, but there are questions about how long that lasts."

According to AmoMama, the mystery lady is singer Samantha Urbani. The outlet reports that the pair started dating in April 2019. Even though Samantha hasn't openly confirmed her romance with the actor, fans are convinced that the two are dating based on her Instagram posts.
