Hilton Upset By Letterman's Jail Questions

Socialite Paris Hilton was visibly upset during an appearance on David Letterman's U.s. TV show on Friday night, when the host refused to stop asking her questions about her recent jail stint.

Hilton, who spent 23 days behind bars in June for violating her probation on a 2006 drink-driving charge, became increasingly uncomfortable and annoyed by Letterman's questions on the Late Show.

After six minutes of jail-related questions, the 26-year-old - who was on the show to promote her fragrance Can Can and upcoming film Repo! The Genetic Opera - said, "There's other stuff to talk about Dave. I didn't come here to talk about this. That was a long time ago."

She added, "I'm sad that I came here."
