When Paris Hilton was asked by ABC News' Dan Harris if she feared her "moment" of fame was over, the reality TV star scoffed, stood up and walked away mid-interview.
Just before the question was posed that set her over the edge, Harris asked Hilton, 30, if she worried "that the people who have followed in your footsteps -- like Kim Kardashian -- are overshadowing you?"
"No, not at all, " she replied flatly.
Hilton even claimed she wasn't concerned about the dismal ratings of her Oxygen reality show, The World According to Paris. Watching her and then-beau Cy Waits' lack of "chemistry" on the show was what she told Harris caused her to break things off with him in June.
But off camera, the blonde told her publicist she didn't want the interview being used.

Hilton later recovered from her tantrum and explained to Harris that she wasn't past her prime. "I've been in this business for fifteen years now, so it's been a very long time," she said with her hands on her hips. "Just like any other business person or someone in the industry, it's always important to reinvent yourself and come up with new projects."
