Fergie's Fergie performance

May 15, 2007, 12:00 GMT

Sarah Ferguson, the Duchess of York, has asked Black Eyed Peas singer Fergie to perform at a charity event she is organising.

The duchess - nicknamed Fergie - decided to call in the favour after taking note that singer Stacy Ferguson had called her first solo album 'The Dutchess' and filmed the video in London sporting a tiara as a cheeky reference to their shared nickname.

Sarah contacted the 'My Humps' singer and asked her to perform at a concert she is organising for UNICEF (The United Nation Children's Fund) at New York's Cipriani Wall Street on May 17.

The 32-year-old singer has agreed.

This will be the third annual Cipriani Wall Street Concert Series, running over seven nights, and will this year benefit the US Fund for UNICEF and the Sarah Ferguson Foundation.

Sponsors Deutsche Bank and Cipriani expect to exceed the $1.2 million raised last year for amfAR.

As well as Fergie, 50 Cent, Lenny Kravitz, The Pussycat Dolls and Andrea Bocelli will also perform.

The duchess established the Sarah Ferguson Foundation last year to help make a difference in the lives of families and children throughout the world.

The foundation aims to mandate funds generated from the duchess' commercial and charitable projects to provide financial support to various charities including UNICEF.
