Tayla posted two images of herself posing with her "boyfriend".
"Cats out of the bag 🐱🥇 Most amazing week away surrounded by friends, family and my boyfriend at @templefarmhouse_byron 💕"
Dom was quick to follow, sharing three romantic snap shots.
The confirmation comes after almost two months of the pair looking particularly close.
Things took a huge turn when on September 11, 21-year-old Tayla posted a snap of herself being cuddled by Dom on Macmasters Beach with the caption, "Last night of holiday mode before going back to reality tomorrow 🐚 Central Coast provided some much needed down time with a great group of people. 💕"
Meanwhile, Dom, 26, posted a picture of himself smiling while Tayla playfully stuck out her tongue. He kept the caption simple with a, "#HolidayMode"
Tayla won Love Island Australia with her boyfriend at the time, Grant Crapp. Dom was paired up with Shelby Mills. Both romances fizzled.
