Move over, Diana Ross and Stephanie Mills. There’s a new lady easing down that yellow brick road with Lion, Tin Man and Scarecrow. It’s just been announced Ashanti will star in the Broadway revival of “The Wiz.” The summer production will run June 12-July 5 at the New York City Center. With her music career seemingly on chill mode, Ashanti appears to be turning her sights to acting. A few of her latest film credits include “John Tucker Must Die” and “Bride & Prejudice.” This will be Ashanti’s first stint on the Great White Way, and we’ll be watching.—ZH
