Daniel Radcliffe: I Thought Justin Bieber Was A Woman (VIDEO)

Daniel Radcliffe just cleared up some confusion about Justin Bieber's gender.

"I only heard Justin Bieber for the first time two weeks ago," Radcliffe told MTV News. "I genuinely thought it was a woman singing. I'd never heard it before. Is it big in England yet?"

Radcliffe admitted he is "out of the loop when it comes to pop culture" but he is a big fan of Lady Gaga's.

"I think she's kind of amazing," he said. "She's really got a voice. My god. Not my kind of music, particularly, but she can really sing."
