Paris Hilton walked out of an interview after it was suggested her "moment" could have "passed".
The socialite stopped an interview with ABC News in the US after being asked if poor ratings for her show 'The World According to Paris' and the prominence of other reality TV stars could suggest her popularity is waning.
She replied: "No, not at all."
However, when the host pushed the star, asking: "Do you ever worry about your moment having passed?" She looked at her assistant then stopped the interview.
After regaining her composure, the 30-year-old consented to re-start the chat and explained how she is planning to move forward.
She said: "I've been in this business for fifteen years now, so it's been a very long time.
"Just like any other business person or someone in the industry, it's always important to reinvent yourself and come up with new projects."
Paris starred in her first reality TV show, 'The Simple Life' in 2003, and has been in a number of series since, including three versions of 'Paris Hilton's My New BFF' in the US, UK and UAE.
Kim, meanwhile, has starred in 'Keeping Up with the Kardashians', which has aired since 2007 and is currently one of the most talked about stars in the US ahead of her marriage to Kris Humphries - which is also expected to be televised â later this summer.
