Tennis star Frances Tiafoe headed to Kansas City on Sunday, to join Taylor Swift, Travis Kelce and Patrick Mahomes in a surprise sporting crossover.

The world No 18, and two-time US Open semifinalist, was among the crowd as the Chiefs moved to 9-0 with a dramatic win against the Broncos.

After the game, Tiafoe’s girlfriend – and fellow tennis player – Ayan Broomfield posted a series of photos from inside the VIP suite at Arrowhead Stadium.

The couple – who have reportedly been dating since 2015 – were pictured celebrating alongside Swift and Kelce, as well as Patrick and Brittany Mahomes.

Tiafoe and Broomfield were earlier treated to a thrilling game which ended in a 16-14 Kansas City victory.

The back-to-back Super Bowl champions trailed for much of the game and needed a blocked field goal – in the game’s final moments – to maintain their perfect record.

Many of Tiafoe’s rivals are currently in Turin, Italy, competing in the season-ending ATP Finals.

Taylor Fritz is the only US representative in the tournament, leaving Tiafoe the chance to soak up some NFL action.

Meanwhile, Kelce’s ex-girlfriend Kayla Nicole reportedly believes Swift is the reason she no longer speaks to Kansas City Chiefs WAGs.

Nicole dated Kelce on and off for five years before his romance with Swift and she recently made headlines by discussing their relationship on WNBA star Angel Reese’s podcast.

Among other revelations – including that she cannot not speak to Kelce if they ever see each other in public – the influencer revealed she has drifted apart from some of the wives and girlfriends of Chiefs players she used to be close with.

And, according to Marca, Nicole is frustrated that she has been ‘pushed out’ of the group because of Swift’s increased presence at Kansas City games.
