So you think you can dance? We’re told Tanisha Scott — a dancer and choreographer who’s worked with Jay-Z, Alicia Keys, Rihanna and Sean Paul, and appeared in videos for Ne-Yo and Ludacris — has been chosen to choreograph and guest-judge auditions for the Brooklyn Nets’ dance team. Auditions for the new, Crunch Fitness-sponsored crew will begin Saturday at Long Island University in Brooklyn. Crunch’s Fort Greene location is putting on weekly intensive training sessions for aspiring Nets dancers. The squad will be entertaining fans at the Barclays Center next season. Scott was also choreographer on “Notorious,” the Notorious B.I.G. biopic.
