HERE is a long article about Rob. I have selected some parts:
Robert is too smart to be stereotyped.
After gaining his heartthrob status in Harry Potter, he changed tack to play the troubled artist Salvador Dali in next year's raunchy Little Ashes.
He says: "I didn't want to get stuck in pretty, public school roles, or I knew I'd end up as some sort of caricature.
"Playing Dali has been a complete turning point for me. It's the first part I've had that has required really serious thought. I became completely obsessed with Dali during the filming, and I read every biography I could get hold of.
"He was the most bizarre, complex man, but in the end I felt I could relate to him." Robert is nothing if not pragmatic. A professional actor for seven years, he even had to pay his own school fees.
"I was at a small private school in London," he says. "I wasn't very academic. My dad said to me, 'OK, you might as well leave, since you're not working very hard'. When I told I him wanted to stay on for my A-levels, he said I'd have to pay my own fees, then he'd pay me back if I got good grades."
Robert did - an A and two Bs - but his father didn't pay, which must rankle.
Robert says of the car salesman: "My dad told me a lot of stories. I would never buy a car from him."
But it's clear Robert will have to answer to his family if he displays the slightest sign of diva-like behaviour.
Robert's aunt Monica Weller, from Leatherhead, Surrey, said: "My sister is going to make sure the fame does not go to his head." But she added: "Robert has wanted to be an actor for as long as I can remember. We are all really proud of him."
Robert readily owns up to the fact that he aspires to be Jack Nicholson and Twilight - his first lead role - is set to make him a superstar.
Happily, Robert isn't quite perfect. His American film bosses insisted that he wear a brace to correct his wonky chops. Pro that he is, he didn't have to be asked twice.
Today, his teeth are Hollywood perfect.
Teenage girls, seemingly, just can't get enough of Stephenie Meyer's lusty, yet thoughtful, bloodsucker. Nor, it seems, of Robert. There's no stopping the boy.
