In a candid interview with Moviefone's Angie Argabrite, Robert Pattinson openly states that his fame is "quite stressful in a way, but it's only when you're by yourself." Of that statement he explains further, "When I have my friends around it doesn't make any difference. I just spend a lot of time by myself, and I used to walk around the block by myself in various different cities, and I don't know, you start to feel a bit vulnerable."

"In my eyes, everything just seems ridiculous, like every single day it's like you're walking on the street, and then suddenly you step on something and it just starts moving really, really fast, and you're not entirely sure what direction it's going in, but you can feel the force of it. That's about it," says the British actor when giving an evidence of the instant fame he earns after starring as Edward Cullen in "Twilight." He continues revealing that similar thing happens to his other celeb friends, especially those who star in "Twilight" and "The Twilight Saga's New Moon."

"Now it's quite difficult to even leave the hotel," he says about his life before and after becoming a famous movie star. "And all these random little stories become some way, somehow newsworthy, so you have to be very secretive about everything. Even if you want to just clarify something in the script or something. It's just strange. It's just very different ... It's very strange when you're aware of being observed, I guess."
