Over the weekend, eagle-eyed fans had noticed the model left a flirty comment on the sportsman's latest Instagram.
On drone footage uploaded to his page from his time at Dongara beach in Western Australia, Tayla left three love-heart-eyes emojis below the post.
The pair then engaged in a flirty back and forth conversation, with Nathan even leaving a suggestive "x" at the end of his comment.
"@tayla.damir drone works well 😄 x," Nathan commented.
"@nathanbroad at least one of us has worked it out 😂," Tayla replied.
Tayla then liked a fan comment that suggested the pair were in love.
If that's not confirmation of a relationship, then we don't know what is!
