The 16-year old has made his crushes on older beauties such as Kim Kardashian and Megan Fox well known, most recently saying Katy Perry and Cheryl Cole were "two of the hottest girls in the world."
But in a new interview with Great Britain's The Sun, Bieber doesn't hide his feelings for Harry Potter star Emma Watson, 20. He says of the actress:
"I would love to take her out for dinner. It would be great if she could come to one of my concerts, then we could hang out afterwards. I love the fact she is one of the biggest female movie stars, but has chosen to go back to college. It shows she is really grounded and normal." (thehollywoodgossip)
It's true: Watson attends Brown University and is considered one of the more unaffected child stars the entertainment industry has ever seen.
She is dating George Craig, however, and we aren't a fan of her new haircut. Justin could probably do better. Who do you think he should date?
