Britney Spears to Appear on Madonna Tour, Sort of

As the rumors continue to swirl about the nature of relationship with baseball star Alex Rodriguez, Madonna has announced that Britney Spears will tape a song that will air during the Material Girl's "Sticky & Sweet" tour.

Madonna's rep, Liz Rosenberg, confirmed the collaboration.

"Britney's segment film within the next week or so," she said. "Madonna specifically asked to work with Britney again."

NO GIRL-ON-GIRL REDUX: Madonna and Britney Spears are best remembered for the best kiss ever, but this time, the latter will only appear on video, unfortch.

So glad the stars â€" who famously "performed" at the MTV Video Music Awards in 2003 along with Christina Aguilera - will reunite, albeit virtually.

Good stuff. Taped is probably best, too. Madonna could have probably cajoled Britney Spears into performing live, but ... we all know she can't.
