“Britney has been recording videos for Madonna‘s tour. The first sees her in a hoodie trapped in a lift “cracking up and going mental”, before delivering her “It’s Britney, bitch” line. This kick starts a mash up of “The Beat Goes On” and “Piece of Me.” The video for this has Madge and Brit mummified. Men wearing nothing but leather thongs unwrap them, to reveal the scantily-clad singers getting it on.” [popbitch]
