britney spearsBritney Spears is set to team up with Madonna for the older star’s forthcoming world tour - but only for a video link.

Madonna’s spokesperson Liz Rosenberg yesterday confirmed: “Britney is going to film something for Madonna’s show in the next week or so.”

While Britney is not thought to be performing with Madonna in person, Rosenberg couldn’t give any further details about what was set to be filmed, and where it would take place, because: “I don’t know. It’s a secret.”

The Sticky & Sweet Tour, to accompany her new album Hard Candy, begins in UK and Europe next month and reached the US in October.
