NEW YORK Nov. 20 — Socialite Paris Hilton, star of an upcoming Fox reality series and an inadvertent Internet icon, is pulling out of her announced interview on David Letterman's "Late Show." Hilton was to have appeared Nov. 26 on the CBS late-night show,  the network said Wednesday.

But on Thursday morning, a spokesman for Dan Klores Communications, the public relations firm that represents Hilton, said the 22-year-old was scrapping all planned media appearances to promote her new TV show.

The heiress to the Hilton hotel fortune co-stars in the upcoming Fox series "The Simple Life," in which she and Nicole Richie, Lionel Richie's daughter, live on a farm for a few weeks. A two-part premiere airs Dec. 2-3.

The spokesman said no slight on Letterman was intended, and that this was a case of miscommunication. He added that Hilton wants to keep a lower profile because of the extraordinary amount of attention she's received from her now-ubiquitous Internet sex video tape.

Paris Hilton said this week that she was "embarrassed and humiliated" that a homemade sex video she shot three years ago with then-boyfriend Rick Salomon has been making the rounds online.
