Daniel Radcliffe was sure Justin Bieber was a girl.
The Harry Potter star admits he struggles to keep up with current hot pop stars, but had heard Bieber's hit Baby on the radio.
However, Radcliffe believed the 16-year-old's high-pitched vocals belonged to a female.
He tells Mtv.com, "I only heard Justin Bieber for the first time two weeks ago. I genuinely thought it was a woman singing. I'd never heard it before. I'm so out of the loop when it comes to pop culture that I kind of don't even try anymore".
But there is one superstar The Harry Potter star can't help but notice - he's a huge fan of Lady Gaga. He adds, "I know who Lady Gaga is. 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".
