Legendary pop star Boy George has shown his support for embattled British royal Prince Harry, branding his naked picture scandal "cheap" and "rubbish".

The third-in-line to the throne was dealt a blow on Tuesday when editors at website TMZ.com published two images of the playboy prince.

The photos show the royal stripped off during a party in his suite a hotel in Las Vegas, where he is currently enjoying a break with friends.

A spokesman for Prince Harry has declined to comment on the scandal, but former Culture Club star Boy George has hit out at the celebrity news website on Twitter.com for publishing the images.

He writes, "Prince Harry, where was his security? People are so cheap, such rubbish photos! The Queen should behead TMZ and send the b**ches to da (sic) Tower."
