British actor Daniel Radcliffe has made a rare public appearance with his girlfriend of 10 years, Erin Darke.

The 32-year-old Harry Potter star took the American actress to the March 14 New York premiere of his movie The Lost City, which also stars Sandra Bullock and Channing Tatum.

While the long-term pair have attended various industry events in the last decade, they rarely posed together on red carpets. In fact, the last time they were seen together on the red carpet was at a Broadway event in 2018.

Daniel Radcliffe and Erin Darke attend a screening of The Lost City on March 14 in New York City.

The couple first met on the set of the biopic Kill Your Darlings in 2012 — a film that required the co-stars to film an intimate scene. 

"That's a wonderful record of us flirting for the first time," he told Playboy magazine in 2015. "There's no acting going on — not from my end, anyway. There's a moment when she makes me laugh, and I'm laughing as me and not as my character. She was incredibly funny and smart. I knew I was in trouble."

"One of the first things we bonded over was how much we really love what we do and there's something that's really beautiful and really lovely about being with someone who just innately understands that about you," she said.

"He helps me make self-tapes sometimes. He's a great reader, by the way. We're both incredibly supportive of the other person's career."
