They started off as sweet-faced kids in the first 'Harry Potter' movie, but Daniel Radcliffe, Emma Watson and Rupert Grint have all grown up just as their popular characters have. In this StarStyle gallery, see how the close friends (on and off screen) have transformed from young wizards to young adults, trading in their magic cloaks for glamorous red carpet wear.

As Emma Watson turned 18 years old on Monday, she had two things to celebrate -- her birthday and her newly granted access to the $20 million fortune she's earned from her 'Harry Potter' movies. That's one wealthy wizard!

But don't expect this level-headed actress to be breaking the piggy bank on a massive shopping spree. Emma is backed by a team of financial advisers, and, according to Britain's Daily Mail, she is required to make low-risk, high-interest investments and take classes on how to be responsible with her money.
