Tina Turner

With her sultry voice, Tina Turner could literally phone in a performance and still set the night ablaze. But a show-stopping turn at this year's Grammys confirmed that at age 68, she isn't ready to hang up her dancing shoes — a point Turner is driving home with her first world tour in nearly a decade. Expect more than two hours of nonstop hits (including perennial karaoke favorites "Proud Mary" and "Private Dancer"), many costume changes, and four backup dancers choreographed by Toni Basil (who brings her lifelong fascination with street dance to the otherwise glitzy proceedings). When the eternal Turner takes the stage, the footlights will reveal yet another of her many spectacles — the stiletto-heeled strut of those legendary legs.
