Daniel Radcliffe wants to find out what Justin Bieber's secrets are.
The 25-year-old actor plays Ig Perrish - who grows horns that can help him read other people's minds - in fantasy thriller 'Horns' and would love to use them on the 'Baby' hitmaker.
When asked who he'd like to use Ig's power on, he told MTV UK: "Maybe Justin Bieber. Just because you hear so much stuff about him that you are just like, 'I want to really know, I want to get to the bottom of this!' And with horns, I would be able to."
Meanwhile, Daniel recently revealed that his girlfriend Erin Darke is a big fan of the horns he wore in the movie.
He recently said: "She loves them. How could you not?
"They're glorious and I hope very attractive."
According to Daniel, things are going "great" between the couple, who met in 2012.
For his part in 'Horns', the 'Harry Potter' star had to film a sex scene with Juno Temple and he revealed that it was easier to film with his co-star because they had gotten to know each other well.
He said: "My previous sex scene was with a man. And also with a man who was not a principal cast member of the film, so I didn't know him that well.
"At least with Juno we had a lot of time to know each other well. I can't imagine shooting one of those scenes with someone you hate. It would be horrible!"
