Princess Beatrice stole the spotlight during her cousin Prince William's royal wedding with her crazy bowed hat.
The blush-colored, towering Philip Treacy creation will be auctioned off for a good cause. "She's putting it up on eBay to auction it for UNICEF and for Children in Crisis," Beatrice's mother, Sarah "Fergie" Ferguson said on Wednesday's "Oprah Winfrey Show."
Fergie also expressed regret over not getting invited to the wedding. "It was so difficult, because I wanted to be there with my girls and to be getting them dressed and to go as a family," she admitte. "And also, it was so hard because the last bride up that aisle was me and I knew all those feelings."
While her ex-husband Prince Andrew and their daughters were in London, the Duchess of York was thousands of miles away vacationing in Thailand.
Still, she wished the best for William and Kate, and reflected on how his mother Diana would've reacted to their wedding. "I think Diana would be so proud of her son -- of both of them. They did a great job and I sort of really love the feeling that sort of Diana and I -- we both weren't there, but I'm here to say how proud she would have been," Fergie said. "And Kate looked utterly beautiful."
