Janet Jackson + Mindless Behavior

However disconnected from reality she may occasionally appear, Janet Jackson knows that her pop-chart presence has diminished in the age of Katy and Ke$ha. So on her current world tour, Jackson is sticking doggedly to the hits that made her one of the planet’s biggest stars: “Nasty,” “Black Cat,” “That’s the Way Love Goes.” The show’s called "Number Ones: Up Close and Personal" (after the singer’s double-disc 2009 best-of), but it might as well be titled "Look, Bitches: I Was Doing This Back When You Were Dreaming About It." Reports from the road indicate that she’s singing and dancing with renewed precision.
