As far as WAGs of professional tennis players go, the story of Kristina Milkovic and Marin Čilić is arguably the most fascinating of them all, at least in modern times. The Bosnian pro tennis player was a huge underdog during the 2014 US Open, but against the 100-1 odds, he would go on to take home the championship trophy.
A lot of his successes at the time were attributed to his girlfriend, Kristina. According to the 6-foot-6 pro tennis player, her background in psychology helped him overcome the demons that arose from his four-month drug ban. They tied the knot in 2018 and introduced a son, Baldo, into the world.
