Oprah Winfrey has recalled the "big mistake" she made while interviewing Sally Field

Appearing on Rob Lowe's 'Literally' podcast, she said: "My big mistake:

I asked her, 'Does Burt sleep with his toupee on?'

"I even say now, I cringe to even think that I asked that question. But I asked it because the producers are like, 'You have to ask, you have to ask, you have to ask. That's what everybody wants to know.'

"And so I asked it, and she went cold on me. She shut down, and I could not get in again."

Now, Oprah - who has gone onto become one of the biggest names in television with a great reputation for her interviews - admitted she shouldn't have followed that line of questioning, and she "deserved" to be shut down during their chat.

She added: "It was like, 'Whoa, Sally went cold on me on live TV'.

"I deserved it, I deserved it, I deserved it, 'cause that is such an inappropriate question."

'Wayne's World' star Rob - who worked with Sally on 'Brothers & Sisters'

- reflected on his own experiences alongside the 74-year-old actress.

He joked: "She's one of the most amazing actors I've ever known, but when Sally goes cold, it's like Khrushchev in the Cold War. She will bury you."

Oprah, 67, has opened up about the embarrassing incident in the past, and she back in 2005 she described the experience as "awful".

She said at the time: "Sally Field used to date Burt Reynolds and I asked this awful question. It was a bad question. I wouldn't do it today."
