Sugababes will be among the acts to perform at an upcoming music festival hosted by Prince Edward.

The event, being held to celebrate the 50th anniversary of the Duke of Edinburgh Award, will take place in Windsor Great Park over the weekend of July 22.

Lemar, Craig David and the Sugababes are some of the acts lined up to play alongside unsigned artists, who can apply by sending in a demo to a judging panel.

In a statement, the Sugababes noted: "It's quite an honour to be invited by HRH Prince Edward to perform in front of Windsor Castle. We can't wait to meet him and thank him ourselves as we've heard he's quite cheeky. All in all, we're just proud to be supporting a great charity in its 50th year... from everything we've heard the Royal Family certainly know how to party. We hope our fans will come and join us."

The Live Life Loud festival will also contain an entertainment area where participants can indulge in adventure and extreme sports, such as rock-climbing and catapulting.
