Los Angeles, CA (CNS) - Madonna is reportedly planning an explosive dance routine for her appearance on Britney Spears "Circus" tour this year. The two are also rumored to appear together for the Toxic singer's upcoming comeback world tour.

Madge is said to be joining the "Womanizer" singer as a special guest, after Britney performed with Madonna in Los Angeles last November. Spears hired Jamie King for the tour - the same choreographer the Queen Of Pop has used on her last three tours.

Madonna's rep, Liz Rosenberg, however still has not confirmed their tour. Their choreographers are working overtime to figure out some special moves for the two gals to dance out together on stage, E Online reports.
