Paris Hilton, the 24-year-old star of television’s “The Simple Life” reality show, provoked controversy recently by appearing scantily clad in a Carl’s Jr. burger commercial.

The hotel heiress is engaged to Greek shipping heir Paris Latsis, a grandson of John Latsis, the last of Greece’s shipping billionaires from the postwar boom years, who died in 2003 at 93.

Kathy Hilton stars in NBC’s “I Want to Be a Hilton,” in which she guides 14 young contestants through a variety of weekly challenges in the New York social scene, ranging from art and culture to beauty and fashion. The winner of the show, which premieres June 21, will receive a $200,000 trust fund.
