Actress Emma Watson, who earned millions playing Hermione Granger in the " Harry Potter" movies, doesn't know how to spend her money.

"I have way too much money to know what to do with it," showbizspy.com quoted her as saying. "I bought a laptop, and a Toyota Prius when I passed my driving test, but that's the most expensive things I've spent my money on outside my education," she added.

Watson also admitted that she prefers being single as she would not make a good girlfriend.

"It's rubbish being my boyfriend. People are constantly coming up to me, I'm always working. I don't have a boyfriend at the moment. It feels good, actually. It's nice to be selfish," she said.
