New Delhi, July 6 : Rupert Grint, who plays Ron Weasley in the ''Harry Potter'' film franchise, says that he doesn't know what to do with all his money.

Grint, 20, only realised how rich he was when he was featured in Forbes'' list of top earning young superstars in 2007, reports the China Daily.

"There was a moment where I remember thinking, ''I have no idea what I''m going to do with all this money,'' " he said.

Despite his worries, the star has made every effort top put a dent in his wealth, buying a pick-up truck, banjo, ice cream van, hovercraft and a home for his parents - but still prefers other aspects of fame.

"Money isn''t the only good thing about the job. I''ve gotten to meet heroes like Robin Williams. Although, my grandfather spent the whole time doing Mrs. Doubtfire impressions," Rupert said.

Rupert has also revealed that both he and Daniel Radcliffe have crush on their ''Harry Potter'' co-star Emma Watson.

He told FHM magazine: "Emma''s a pretty girl. Have Daniel or I ever hit on Emma? Well, she''s quite popular with the cast. As for who has the worst crush on her - me or Daniel - I''d rather not say." (ANI)
