Paris Hilton felt "purposefully humiliated" during an interview with David Letterman.
Footage from the 2007 encounter went viral last month, when the talk-show host was criticised for questioning the 40-year-old star about the brief time she spent in jail for parole violation, and Hilton has now revealed she felt that his approach "crossed a line".
She said: "I was just getting so uncomfortable and I was so upset ... Just being up there, it was like he was just purposefully trying to humiliate me.
"It was just very cruel and very mean."
Hilton, 40, revealed the interview was her first in months and that she agreed to take part as she felt she was in a "safe place" after being interviewed by Letterman several times previously.
