Veteran pop star Boy George has hit out at Madonna for her ambitious streak - and insists the Material Girl is as cold as ice.

George, 43, has a bitter and long-running feud with the famously business- minded Madonna, and has previously admitted to being jealous of the megastar.

He says: "If Madonna were a drag queen, she would be called Ruth Less.

"I don't think the word 'warm' comes to mind with Madonna. Ice is the word that springs to mind."
