If Kanye West follows through on his presidential ambitions, his wife, Kim Kardashian, will be ready: She just became the proud owner of Jackie Kennedy’s Cartier watch. The couple bought it at auction in New York, for a stratospheric $379,500, TMZ reports... Kennedy had been given the watch by her brother-in-law Prince Stanislaw Radziwill, according to the gossip site. It’s engraved with the date February 23, 1963, and commemorates a hike the prince participated in to support President Kennedy’s goal of making Americans healthier.
