Teen singer Justin Bieber has admitted he has a crush on Harry Potter babe Emma Watson.

Bieber, 16, recently revealed his love for the older lady when he said his perfect girlfriend would be Cheryl Cole.

He has now said he would love to take Watson, 20, out on a date.

He said: "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."

Watson is said to be dating model George Craig.
