Paris Hilton stops interview after being asked if 'moment has passed'

Paris Hilton appeared to briefly stop an interview with ABC after being asked whether she thought her moment in the spotlight has passed. 
Footage shown on GMA this morning shows Dan Harris asking Hilton about competition from other socialites and the ratings for The World According To Paris. 
Hilton tells Harris that she doesn't feel overshadowed by stars such as Kim Kardashian and insists that she is happy with the ratings for her reality show, before Harris then asks if she thinks her "moment has passed". 
Hilton responds by looking off camera and staying silent, prompting Harris to ask: "Do you want to wrap up?"
Former Simple Life star Hilton then briefly walks off camera, although she does then return to allow Harris to continue with the interview, even giving him a hug at the end of their conversation. 
"I've been in this business for 15 years now so it's been a very long time and like any other business person or someone in the industry it's important to reinvent yourself and come up with new projects," she says. 
Hilton has yet to comment on the interview, although she did encourage followers on her Twitter account to tune into GMA for the talk yesterday.
