Emma Watson thinks it's funny when people recognise her on the London Underground. The 20-year-old Harry Potter actress told British newspaper Metro: 'The funny thing is people look at me and go: 'Is that the girl from Harry Potter?' And then they shake their heads and say: 'No, it can't be, she's on public transport.' And I'm sat there secretly thinking: 'Ha Ha that's funny.''

Watson, who studies at US Brown university, also said she doesn't know what to do with all her cash.

She added: 'I have way too much money to know what to do with it. 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.'
