Daniel Radcliffe may not have heard of Justin Bieber until recently, but after his recent comments, he’ll certainly be hearing from the pop star’s fans. “I only heard Justin Bieber for the first time two weeks ago,” the Harry Potter star tells MTV News. “I genuinely thought it was a woman singing. I’d never heard it before. Is it big in England yet? I’m so out of the loop when it comes to pop culture that I kind of don’t even try anymore.” He’s not completely in the dark when it comes to music, though. “I know who Lady Gaga is,” Radcliffe says. “I think she’s kind of amazing. She’s really got a voice. My God. Not my kind of music, particularly, but she can really sing.”
