Madonna will perform with Britney Spears in the summer on some of Britney’s performances during her global “Circus” tour, reports The Mirror.
“Choreographers have been asked to create an out-of-this-world dance routine for Britney and Madonna,” a source revealed.
“When Britney joined Madonna on stage for her Hard Candy tour it was very sedate.
This is going to be a high energy dance routine - getting back to what they are both good at, performing.”

EPIC!
