WWW- Eccentric singer Macy Gray has come up with an interesting way to raise money for charity — she’ll perform naked.

The R&B star says she’ll appear in nothing but a pair of Jimmy Choo heels at her London gig on Monday.

Gray will reveal all to raise cash for the Elton John Aids Foundation.

”Never before has a major artist gone so far in aid of a good cause,” a spokesman for the singer said. “Macy was invited to be part of a celebrity auction in which photographs of stars wearing Jimmy Choo shoes will go under the hammer. She wanted to do something special for it so decided that in her photograph she would be naked onstage. It is a very sexy statement.”

The gig will take place at The Coronet in Elephant and Castle, south London. It’s Gray’s first U.K. gig in two years.
