Jack Brinkely-Cook, 27, looked as happy as can be on his last outing with Genie Bouchard. Christie Brinkley's son, 68, visited a beach in Miami, Florida with the 28-year-old tennis player and cuddled and frolicked by the water's edge. He was shirtless and wore only white shorts and a white and blue baseball cap during the party, while she wore a blue and white plaid bikini and had her long blonde hair down.
