Madison McKinley is currently dating the currently ranked-24th men’s singles tennis player in the world– John Isner. However, she’s not a bandwagon girlfriend or fan. The two have been together for many years now, even before his career really started to flourish.
Many people who’ve been following John’s career will recall Madison in the bleachers during each of his major tournaments. The two got married in 2017 in South Carolina, and they have three children together. When she’s not cheering her heart out for John on the court, she’s busy running her jewelry company. You can see what her company, named after herself, is all about on its website.
