Britney Spears video shoot for Madonna's upcoming tour has been halted because the set was not finished in time.
The set features an elevator in which Britney will dance. Insiders have said that once the set is completed "The video will be very deep, you've never seen Britney like this before. It will blow your mind."
Madonna, who has guest starred Britney's video for "Me Against the Music" in 2003, stirred up controversy with some full on girl-on-girl snogging at the MTV Video Music Awards and got her 50 year old mitts on Brit's ex, Justin Timberlake, for her video "4 Minutes", starts her 'Sticky & Sweet tour, in Cardiff, on August 23.
