CIRCUS

Madonna may be spotted shaking a leg with Britney Spears on the latter’s ‘Circus’ tour, according to the ‘Toxic’ hitmaker’s choreographer.Britney had shared the microphone with the Queen of Pop in LA in November during the U.S. leg of her “Sticky and Sweet” tour. Now, Madonna may return the favour if she appears onstage with the ‘Womanizer’ singer, who is scheduled to kick start her comeback tour in New Orleans on March 3. “There has been talk of Madonna making an appearance and there’s so many places we could take that. At this point the main issue is timing” the Sun quoted choreographer Wade Robson as telling US magazine.
