Evan Rachel Wood, 20 Fun Facts

5 of 20: Evan Rachel Wood has admitted to having a case of 'Bieber fever.'

Last month, the actress released a video of herself covering Justin Bieber's 'U Smile' at a karaoke bar in China and Wood also revealed her fandom to 'The Ides of March' director George Clooney on the film's set.

'I'm a big karaoke fan and I also love Justin Bieber unashamedly,' the 23-year-old actress said. 'That is a fact - everyone knows it. So, the whole catalogue was basically in the karaoke machine, so I started singing 'U Smile' and my friend started filming it. We didn't really have a plan to put it online - it just kind of happened.'
