Daniel Radcliffe and his Girlfriend Erin Darke are expecting.

After more than ten years of dating, since first meeting on the set of their 2013 film Kill Your Darlings, the 33-year-old Harry Potter alum and longtime girlfriend Erin Darke have announced their first pregnancy to PEOPLE.

As previously revealed by Radcliffe to PEOPLE, he and Darke, 38, are "In March of last year, she added, "I've got a really nice life. I've been with my girlfriend for a decade, pretty much."

Radcliffe described the experience as " incredibly special and felt lovely," after the two of them collaborated once again on an episode of his TBS series Miracle Workers, although it was more of an irregular occurrence.

"We definitely like [working together], but it's not something we want to do all the time," he said.

"Hopefully we'll get to do more in the future, but we also both write," added Radcliffe. "So maybe we'd write something together at some point, and that would be cool."
