But royals expert Neil Sean said on "The Early Show" some royals are already displeased with the interview because Ferguson has found herself, yet again, in front of a camera.
Sean said, "The queen is less than happy. Prince Andrew is not very happy. And I think Sarah Ferguson, once again, has put both feet in front of her deep. That's why we call it 'Feet-First Fergie.' And I think for her, now admitting on camera that she didn't know what she was doing, not only does it not make it believable, because this wasn't something that was just set up that same afternoon. It was of course planned quite awhile. So I think for Sarah Ferguson, she said once again the wrong thing, once again she's angered the royal family, and I think she should have listened to advice and not bothered with making this interview with Oprah Winfrey."
Ferguson now blames alcohol for her stunt. She now says she was drinking at the time she attempted to sell access to her ex-husband, Prince Andrew, for more than $700,000.
Ferguson told Oprah, "I'm very aware of the fact that I had been drinking, you know that I was not in my right, right place."
Sean said admitting this kind of behavior publicly isn't looked upon favorably by the royals.
"The queen certainly does not believe in speaking up about anything that happens in public life," he said. " ... Prince Andrew tried his best to just say, 'Let's move on from this.' But Sarah Ferguson has to make a living, and what she has to do is sell Sarah Ferguson, which is what she's done time and time again. She's a lovely girl. It seems ... she's continually misguided. But why on earth would you go on a show as huge as Oprah Winfrey and then confess to another problem. (That's) leading to speculation that there are deeper demons within Sarah Ferguson's mind as to judgments of late, basically."
Ferguson also told Oprah she hasn't seen the entire video.
"I haven't actually sat down and watched it," she says in the interview, which will air Monday. "I haven't faced the devil in the face because I was in the gutter at that moment."
Though the hidden camera video does show the duchess with a bottle at her side, some are wary of her claim. CBS News correspondent Elizabeth Palmer said originally, the duchess implied that poverty compelled her to make the deal. Divorced from the prince in 1996, she claimed her annual allowance was just under $25,000 dollars. But the royal family, furious, reportedly paid her $4.5 million, although they didn't make her sign a confidentiality agreement -- something they may now regret.
With Oprah, "Early Show" co-anchor Maggie Rodriguez pointed out, Fergie has again brought up her financial woes and low annual allowance from the royal family for her plight.
Could the queen potentially give her more money?
Sean said issues with the new government may hamper the queen's ability to get more money for even her own needs.
He explained, "(It's) not a good time, because now, maybe, the government will think that the queen may give some of that money to Sarah Ferguson. What you have to remember is that Sarah Ferguson isn't part of the royal family. She's just the Duchess of York. Her children, of course, the daughters, are on the royal civil list and they're looked after. Basically, Sarah Ferguson needs to find some way of earning some income. It's nothing to do with the royal family whether they support her or not. And I think she seems to need to get a grip of that moment and realize that the freeloading days may be over."
As for earning money, Sean says Ferguson may have to leave the U.K. to find work.
"We already know that Donald Trump likes the idea of her on 'The Apprentice.' Over here, it's difficult for her to be on television. The (British Broadcasting Corporation) couldn't really be seen to giving away our public-funded money over to Sarah Ferguson to appear on reality shows. It just wouldn't wash. It's very testing times for Sarah Ferguson. Where she goes remains to be seen."
