He may be very busy shooting films and attending movie premieres but Daniel Radcliffe's girlfriend Erin Darke doesn't feel neglected at all. In fact, the 'Horns' star tries hard to be there for her every chance he gets.

In an interview with Marie Claire, the 'Harry Potter' alum shared a romantic gesture he did for his lady love - and it's reminiscent of his role in his latest romantic comedy movie.

"I think this is the part where I play someone most like myself," he told The Daily Mail in a past interview about his role as Wallace. "I'm definitely the geeky guy who wants to be in a relationship. And it was a big thing for me to do a modern-day romance."

In 'What If,' Racliffe's character, Wallace, flies to Ireland from Canada to profess his love for Chantry (Zoe Kazan). However, Chantry had already flown back to Canada that same morning making Wallace race right back home.

Just like how Wallace failed to surprise Chantry in the movie, Radcliffe's romantic surprise for his real life girlfriend didn't go quite as planned. It thankfully wasn't as bad as Wallace's screw up though.

"I was going to fly to New York to surprise her once, but then I kind of ruined my own surprise the night before because I was on the phone to her and she'd had a terrible day and was in a bad mood and I wanted to make it all go away," the 25-year-old actor shared.

He eventually ruined the surprise, telling her, "I just went, 'Guess what? I'm going to be there tomorrow, we're going to see each other.'"

Although he didn't share her reaction, Daniel Radcliffe's girlfriend surely would have been quite ecstatic.

He previously called Erin Darke his best friend and believes couples should also be the closest of friends aside from being in love.

"I'm going out with my best friend at the moment," the 'Woman In Black' actor previously told People. "And that's, I think, the way it should be."
