Sarah Ferguson: 'I rang Fergie over nickname'

Sarah Ferguson has said that she rang up Black Eyed Peas frontwoman Fergie after she heard that the singer wanted to trademark her nickname.

The Duchess of York revealed on CNN's Piers Morgan Tonight that she was happy to be known by the name herself.

Ferguson said: "At last, someone remembers good ole Fergie. You know, on my wedding day, I think there were more people walking their dogs, calling their dogs Fergie. I remember walking through the park and everyone going, 'Fergie!' Now, what have I done?

"The Black Eyed Peas [singer Stacy Ann Ferguson], when she said she tried to copyright Fergie, I rang her up and I said, 'You know, you're trying to copyright Fergie. You've got an album called The Duchess. Excuse me, give me something!'"

She added: "She said, 'Oh, hello'. I said, 'I tell you what, you know what? Come and sing for my charity'. And she did. She came to Wall Street and she sang for the Sarah Ferguson Foundation.

"And we raised lots of money - we raised a lot of money for building schools. And she said, 'Well, my mum was a teacher', or is a teacher. And so, she loved doing it. She's very kind."

Black Eyed Peas were recently forced to cancel a free show in New York because of thunderstorms.
