CHICAGO (MarketWatch) -- Pop star Madonna has inked a deal with Smirnoff vodka to participate in a promotion called "Global Nightlife Exchange" that will help her find a new dancer for her next concert tour. The Nightlife Exchange aims to get 10 million people to "discover, share and swap the most original nightlife experiences" in 50 different countries. Fans can enter a dance competition online with the finalists competing in front of Madonna. "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," said Madonna, whose full name is Madonna Louise Ciccone, in the announcement. Smirnoff is owned by London-based beverage alcohol.
