Pop superstar Madonna is launching a competition to find a dancer to join her next tour.
The Material Girl has teamed up with Smirnoff Vodka and asked fans to submit a 60-second video about themselves, before they get the chance to show off their moves in front of the star.
As part of the campaign, fans from across the globe are being asked to swap their best nightlife experiences on social networking site Facebook.com to create the "world's biggest nightlife exchange".
Meanwhile, 50 parties will also occur simultaneously in different countries on 12 November (11) - and Madonna will attend one Smirnoff Nightlife Exchange Project bash to judge a dance-off by selected competitors.
She says, "What attracted me to the Smirnoff Nightlife Exchange Project is the combination of participating in the celebration of nightlife around the world and the opportunity to discover the world's best unknown dancers. The best dancers are always in the clubs looking for the most original experience, just like Smirnoff is doing."
The winner of the dance contest will get the chance to perform on the singer's next trek.
