As well as being all kinds of cute on their own Instagrams, a performer from the event told Who magazine that the reality stars were "all over each other" and that Abbie kept "jumping into Nathan's arms and doing the 'Dirty Dancing' lift in front of everyone".
At one point, Abbie asked her Instagram followers to 'dare' her and Nathan, with one fan daring the couple to kiss.
And OH BOY did they get close.
According to both their Instagram stories, Abbie and Nathan then continued the day at a private residence before heading to fancy Sydney restaurant Matteo, with another close friend.
For those that can't quite remember 10/10 hottie Nathan, he was on Ali Oetjen's season of The Bachelorette, but was labelled 'too young' and a 'party boy'. Nathan then went on to star in Bachelor in Paradise.
Abbie and Nathan's PDA comes a few days after the curly-haired gal was labelled a 'homewrecker' by fans, who jumped to all sorts of baseless conclusions after Matt and Chelsie broke up.
"Hey! This is completely false," Abbie wrote on her Instagram Story next to a screenshot of a magazine article that claimed Matt had moved on with her. "Stop writing sh*t like this and driving forward the narrative that I'm a 'homewrecker' or a 'man stealer' because it makes people click and hate me more. :) thanks."
We rate Nathan and Abbie as a couple TBH!
