The glamour swim couple, who split but later reunited back in 2017, are said to have gone their separate ways once more as both prepare to compete at the July Olympics — should the Games proceed.

Based in Adelaide, both Chalmers and Wilson are believed to have remained friends, however there has been no mention of each other on their respective social media accounts since midway through last year — notable given both are prolific Instagrammers and often post dozens of stories per day.

The on-again-off-again pair first started dating in 2015.

Chalmers’ management did not respond to requests for comment.

The swimming sweethearts first hooked up in 2015, shortly before Chalmers shocked the world with his unexpected win in the 100m freestyle at the Rio Olympics.

Just 18 at the time, Chalmers stunned all with his win, defeating the much more fancied American Nathan Adrian and fellow countryman Cameron McEvoy in the process.
