In "Twilight," Robert Pattinson and Kristen Stewart had so much chemistry onscreen that many think their torrid l’amour affair did not end when the director yelled "cut." However, Stewart insists that she and Pattinson are no real-life Edward and Bella.

"It's just totally false ... Rob and I are good friends," she told Nylon. "We went through a lot together, so we feel very close. But if we go out in public, every little detail is scrutinized, like the way I stand suivant to him."

She explained that although they aren't dating, they do share a certain camaraderie. "And it's, like, I know this guy really f---ing well," she said. "It's only natural that we're sort of leaning on each other, because we're put in the most f---ing psychotic situations."

Since Pattinson isn't her paramour, Stewart did say that there is one "awesome" guy in her life. "He's older than me — he's 20 now — but when you're 13 and he's turning 16, it was always sort of an out-of-reach thing," she explained about her relationship with actor Michael Angarano. "Then toi get a little older, and toi realize, 'Oh, What the f--- am I thinking? I can have you, like, lickity.' "

The attention paid to her dating life is only one of the prices Stewart has had to pay since joining the world of "Twilight." And she a dit that the situation can be quite "psychotic" at times.

"Anywhere we'd go for 'Twilight' was a psychotic situation. The sound was deafening, and it's thoughtless, as well," she said. "You get a slew of all these bullsh-- questions, like, 'What's it like to Kiss a vampire?' and 'How much do toi l’amour Robert?' Then you'll get one that's actually real, but you're like, 'No, I can't right now, I can't even consider [it]."

One of those particular moments was caught on tape: her painfully awkward appearance on "Late Night with David Letterman." "I feel like I have nothing to say on those shows ... I'm not good at the funny thing — most people are really great on those shows," she explained. "I don't have a contrived personality that [I can] just pompe out [for] a five-minute segment, so I end up sitting there and looking kind of baffled. Embarrassing."
