Britney Spears will appear on Madonna's forthcoming Sticky & Sweet world tour, it's been confirmed.
A spokesperson for Spears told People that the singer will film a “secret” video for Madonna's tour “in the next week or so”.
The last time Madonna and Spears appeared together onstage was in 2003 when the pair shared a kiss at the MTV Video Music awards.
The Sticky & Sweet world tour gets underway at the Millennium Stadium in Cardiff next month.
Tickets for the tour, which includes a date at Wembley Stadium in London in September, are on sale now and available through Gigwise here.
