"It's not quite as debilitating [as it seems]," Radcliffe explained of his crush on Perry.
But when asked why he didn't approach her in person at a recent event, to say hello and express his undying love for her (obviously), he told DeGeneres:
"I thought I should go up and say hi and then I thought about, 'What if she thinks you're some teenage fanboy?' So I couldn't. I said, 'I'm not going to try, it would be embarrassing.'"
The Harry Potter star added, "She probably knows I have a crush on her. She's not here is she?"
DeGeneres then joked, "She's actually in the next act. She's bringing out a naked statue of you!"
"Oh fantastic, so many of my fantasies," the Brit quipped.
And speaking of nakedness…Radcliffe clarified one important note when it comes to him baring his all in films.
"I'm comfortable with it, but I do like to point out, I don't request it," he said.

"I was having a conversation with another friend of mine who's an actress who has done quite a few nude scenes and I was just saying, 'We're going to start getting called exhibitionists.'"
Radcliffe goes completely nude in the last few movies he's been in, a huge departure from his clean-cut days as Harry Potter.
As a matter of fact, one scandalous moment in particular is getting a lot of buzz lately.
Radcliffe stars in a gay sex scene in his latest flick Kill Your Darlings, which also stars Dexter's Michael C. Hall, Jack Huston and Ben Foster.
The film is a real-life drama about the early days of Allen Ginsberg's friendships with his fellow Beat generation poets.
