Her rapid rise to fame may be a dream come true for Twilight star Kristen Stewart, but it's not all sweetness and light for the young actress.
The 20-year-old has revealed she is often so overwhelmed by her role in the spotlight, that she has to stifle an urge to cry.
"It's not that I'm miserable, it's just that somebody's yelling at me," she says.
"I literally, sometimes, have to keep myself from crying. It's a physical reaction to the energy that's thrown at you."
The actress, who is dating co-star Robert Pattinson, also says she has no intention of talking about her private life.
"I would never cheapen my relationships by talking about them," she says.
"People say, 'Just say who you're dating. Then people will stop being so ravenous about it.' It's like, No they won't! They'll ask for specifics."
