Britney Spears has hired Madonna's former choreographer R.J. DURELL to make sure her much-hyped MTV Video Music Awards performance is a real showstopper. The Toxic singer is rumoured to be opening the VMAs on 9 September (07), and now online reports suggest she's taking her performance very seriously. A source close to Durell tells website, "He is co-choreographing her performance for the VMAs with Nick Flores, who worked with her as a dancer before." The insider reveals Spears and Durell have been working together for "a couple of weeks". Durell, who has danced in movies like Rush Hour 3 and Austin Powers In Goldmember, choreographed three numbers on Madonna's Confessions tour.
