Ivanka Trump will be the face of a new UN “Girl Up” campaign. Andrea Hansen, CEO of Ivanka Trump Fine Jewelry, told us at an event in a Trump Park Avenue penthouse this week: “Ivanka is the first face of this campaign, which improves the lives of girls around the world.” Guests — including dad Donald, husband Jared Kushner, Robert Verdi, Nigel Barker and Gilles Mendel — were treated to a performance by singer Little Boots.
