Britney Spears spending hours holed up for dance practice is, of course, hardly news by this point - but hundreds of fans/hopeful background dancers lining up to meet with the pop princess certainly is! That was the scene at the Millennium Dance Complex yesterday, where Queen B held court as she gave a throng of her fancy-footed fans a chance to join her retinue of dancers - Brit's presence actually drew such a big crowd that she had to stick around until the sun went down! (Given your history with backup dancers, please employ caution when choosing your next team, Brit!)
