Paris Hilton gifting fans to David Letterman

David Letterman is probably off Paris Hilton's Christmas card list. The 26-year-old socialite was less than amused when the US chat show host refused to stop asking her questions about jail.

"I'm not answering any more questions about it," she snapped. "I'm here for my clothing line, my movie and my perfume. I'm not here to talk about that."

Hilton, who served 23 days in prison for driving on a suspended license, found herself the butt of Letterman's jokes when she appeared on his show. After asking her whether she preferred Los Angeles or New York, the talk show host said: "How did you like jail?"
