17-year-old Emma shows how mch she's changed in her new Tatler fashion shoot

As Harry¹ Potter's sidekick Hermione Granger, she plays the perfect pupil with a butter-wouldn't-melt smile.

But as these pictures of Emma Watson prove, the 17-year-old is growing up fast.

In a photoshoot for Tatler, the young actress swapped² her neatly³ pressed Hogwarts school uniform for Yves Saint Laurent and Chanel dresses, cutting an assured figure.

But despite stepping out on the celebrity⁴ social circuit recently, Emma, from Oxford⁵, said she remains⁶ reassuringly⁷ "normal".

"People who try to hide from fame can make it go completely the wrong way," she tells the magazine. "All those huge designer shades make them look like bugs⁸!

" I think the best way to cope is to try and live as normal a life as possible."

Despite her new modelling career, Emma insists she is going to go to university to study philosophy.

She is taking AS-levels in English literature, geography and art history and hopes to study philosophy at Cambridge University.

But Potter fans need not worry: the latest instalment of the popular film series, Harry Potter And The Order Of The Phoenix⁹, opens on July 13, and Emma says she "definitely intends" to do another one.

She admitted: "I would do Harry Potter for nothing. It's not really anything to do with money."
