Daniel Radcliffe and Rupert Grint talk about Rob's fame

Harry Potter star Daniel Radcliffe says Twilight actor Robert Pattinson appears to be dealing well with the pressures of fame.

"I wouldn't have any advice," Radcliffe told the BBC. "He seems to be coping well," added the actor.

Since appearing as vampire Edward Cullen in the Twilight film series, Pattinson has become a huge star.

The 23-year-old appeared alongside Radcliffe in the fourth Harry Potter film, 2005's Goblet of Fire.

Mobbed

He played Quidditch captain Cedric Diggory, who competes alongside Harry in the Triwizard tournament at Hogwarts school.

You have to keep it in some kind of perspective

"I haven't spoken to Robert since we saw each other at the opening of a gallery three years ago," said Radcliffe. "We've been sort of exchanging advice through journalists, bizarrely."

Over the past two weeks, Pattinson has been mobbed by thousands of screaming fans at launch events around the world for the new Twilight film, New Moon.

Speaking about fame, Radcliffe said: "It is totally mad, when people are screaming and going absolutely insane for you.

"Particularly with Robert - the amount of women that would jump on him - you have to keep it in some kind of perspective, by thinking 'well, partly they like me and partly they are just attracted to the character'.

"As long as you don't think 'oh yeah, God they're all doing this - I must be absolutely fantastic'. As long as you do that, you should be all right."

'Quite strange'

Radcliffe's Harry Potter co-star Rupert Grint, who plays Ron Weasley, said Pattinson had "done amazingly" after appearing in Goblet of Fire.

But Grint admitted he had never been comfortable with getting recognised in the street.

"It's never been normal. I'm slowly getting used to it, but it's quite strange," he told the BBC at a launch event for the Harry Potter and the Half-Blood Prince DVD, out in December.

The world of Twilight is populated by fans called "Twi-Hards", or by Pattinson fans who refer to themselves as "Robsessed".

Pattinson described earlier this month how he prepares himself to face thousands of screaming fans: "I always find myself wearing a lot of layers as well so they can't see you hyperventilating."

The actor has recently finished shooting the third film in the vampire series, Eclipse. A fourth film based on Stephenie Meyer's best-selling novel, Breaking Dawn, is also planned.

Meanwhile, Radcliffe and Grint are currently filming the two-part finale Harry Potter and the Deathly Hallows, out in 2010-11.
