While on a conference call with Kathy Hilton on Wednesday, I asked the I Want to Be A Hilton star and proud mom of Paris and Nicky if her famous daughters had seen the new show yet -- and if they had, what did they think of it? "They are in it so I think they liked it," Kathy revealed. "I hope they like it!" When I digged for more details about when they will appear on the show, Hilton said "I can't tell you...I gotta give you reason to watch!" I Want to Be A Hilton premieres Tuesday, June 21 on NBC.
