Oprah Winfrey cites DAME Elizabeth Taylor as her most awkward talk show guest, because the actress banned her from asking personal questions.

Taylor later apologised to Winfrey, who is celebrating the 20th anniversary of her hugely-popular programme, for her behaviour.

Winfrey recalls, "She later apologised to me, because she realised it was such a painful interview. She was in a lot of pain at the time, but I didn't know that.

"I just knew she was causing me a lot of pain. And she started off saying, 'Don't ask me about my husbands or relationships.'"
