The scandalized Duchess of York—who was married to Prince Andrew for 10 years and is mom to Princesses Eugenie and the hideous hat-wearing Beatrice—sat down with Oprah Winfrey to talk about being a royal reject.
And boy, did Fergie really feel crummy about the diss.
"I was not invited," Ferguson admitted in a segment that will air tomorrow, calling the snub "so difficult."
"Because I wanted to be there with my girls...to be getting them dressed and to go as a family," she added.
"I went through the phase of feeling so totally worthless and that [it] was quite right they didn't invite me. Why would they, why would they invite me?" she asked.
"Also, it was so hard, because the last bride up that aisle was me," Fergie added, noting that her wedding with Andrew in 1986 was the last royal hitching at Westminster Abbey.
So she just tried to get away from it all, flying to Thailand, where she hung out in the jungle—but still caught the coverage.
"I chose to go and be in Thailand in a place called Camelia...the jungle embraced me," she said, adding that the William and Kate were amazing to watch and that Princess Di would have been happy.
"I think Diana would be proud of her son," she said. "Both of them, you know? They did a great job."
"I really love the feeling that sort of Diana and I both weren't there," she added. "But I'm here to say how proud she would have been and Kate looked utterly beautiful."
And the 51-year-old duchess, who visited The Oprah Winfrey Show last year after her being caught on video offering access to her ex for $724,000 to a British journalist, once again addressed her own issues.
"I felt that I ostracized myself by my behavior, by the past, by living with all the regrets of my mistakes, that I sort of wore a hair shirt and beat myself up most of the day thinking and regretting why did I make such a mistake? Why have I made so many mistakes?"
Of course, scandal can be good for business. After all, the appearance was in part to push Fergie's new Oprah-produced reality series, Finding Sarah, which debuts in June on OWN.
