Rodman "demanded cash for charity work"

Dennis Rodman shocked a magazine when he apparently asked for money to take part in a charity photo shoot.

Women's mag Cosmopolitan has previously recruited stars including Lenny Kravitz and Eminem for its fundraising series of risqu? centerfolds. They thought they had the Celebrity Big Brother star on board to raise money for a cancer charity as well ? until he is said to have asked for payment of $13,500.

"We approached him about posing for us as part of the Everyman Campaign and he said he would be happy to do so,? a spokesman explained. ?But there was a snag - he was demanding $13,500 for his trouble.

?So he was told in no uncertain terms he would not be required. Some celebrities just do not understand the meaning of charity."
