Dua Lipa bridges generations. During the New York City stop of her Radical Optimism Tour, the pop star, 30, packed Madison Square Garden with fans of all ages: young girls and their dads, friends both old and new and couples whose relationships date back to either the Barbie soundtrack or Mattel itself. All of them got their money's worth on Saturday, September 20, as Lipa danced the night away for her third of four sold-out shows at the world's most famous arena.
