Sarah Ferguson's interview on 'The Oprah Winfrey Show' (weekdays, syndicated) was looping all day Wednesday on BBC World News with a sound bite about her not being invited to the much-hyped wedding of Prince William and Kate Middleton. But she had another, much more personal moment on the show where she confessed, "I blew it," talking about her marriage and her life.

Ferguson was married to Prince Andrew, making her the Duchess of York. That marriage ended in divorce in 1996. Further, she was involved in a scandal about trying to sell access to the prince, and has been reported as having financial problems. Hers had been the last big royal wedding before Prince William and Kate Middleton.

"I had it all and I blew it," she said. "And I made mistakes."

Winfrey presented Ferguson with a photo of herself on her wedding day, and asked what Ferguson would say to her younger self.

"I'd say, 'Sarah, do you have any idea of who you are?'" Which is either ironic or appropriate, because Ferguson has a new show coming up on Winfrey's network, called 'Finding Sarah: From Royalty to the Real World.'

On this final season of 'The Oprah Winfrey Show' (weekdays, syndicated), Winfrey has made a recurring bit out of surprising her guests with their former co-stars. She's surprised Diana Ross with Billy Dee Williams, and Susan Lucci with all of her former TV husbands. Today, she surprised Meredith Baxter with her former 'Family Ties' co-star Michael Gross.

Baxter spoke about Gross and his wife having lent her a shoulder to cry on during a stressful time in her life. "Michael is the dearest man who walked the Earth," Baxter said. "He's just such a sweetheart." Winfrey then noted that Gross had wanted to be there for Baxter again, on this show, when the audience started cheering, and Baxter realized Gross was walking onto the set.

"You look just like you do on TV," Winfrey said as producers brought out an extra chair for Gross, officially reuniting Mr. and Mrs. Keaton.

David Arquette and Courteney Cox have had to bear public scrutiny during their separation, and Arquette didn't help himself when he called in to Howard Stern's radio show to make some private details public. Arquette was on 'The Oprah Winfrey Show' (weekdays, syndicated) today to talk about the call.

On the call to Stern, Arquette had revealed details about his sex life with Cox, and Winfrey asked what he regretted about that. "That I was drunk, that I wasn't coming from a place of honesty and authenticity," said Arquette.

Susan Lucci has been playing Erica Kane on 'All My Children' for more than 40 years, and in that time she's racked up a lot of TV husbands. Today on 'The Oprah Winfrey Show' (weekdays, syndicated), she was reunited with all eight of them.

Oprah presented Lucci with photos of her character's husbands on a giant curtain and asked her about them. Lucci said she had great chemistry with all of the actors and thanked her casting director.

Oprah then asked which character was hottest in bed as the audience cheered for their own particular favorites. "Look at these guys," said Lucci. "How do you make a choice? Which has been Erica's problem."
