Britney Spears will be performing a 'bandage' sex show with Madonna on her 'Sticky and Sweet' world tour.

The pair will be wrapped up, head-to-toe, in bandages, which will gradually be unravelled by male dancers in leather thongs.

A source told The Sun: "It's classic Madonna, probably the raunchiest stuff she has ever done. It leaves nothing to the imagination and will be very controversial.

"Britney and Madonna unwrap like mummies to appear together almost naked apart from tiny leather bondage pants and knee-high boots. They then dance closely together, pressing their hands and bodies together.

"There will be big rows over whether it's sexy, shocking or both."

The controversial Spears will also be performing Madonna's 1995 hit 'Human Nature'. Spears has filmed a scene — to be shown on 20ft screens during her performance — in which she has a mental breakdown after being stuck alone in an elevator.

The source added: "We'll see her going crazy in an enclosed space — screaming, pulling her hair and banging her fists against the lift’s walls as it gets stuck between floors.

"She really loses it."
