Earlier in the day, the loved up couple were spotted on their date walking through a local park together hand-in-hand.
At one stage, the happy couple appeared to share a serious conversation, possibly what is to come on the current airing of the show...
However, the conversation took a brighter turn and the pair were seen laughing and joking together again.
It was not long before romantic Bill was dropping her off at her destination and sharing a VERY intimate kiss in his car.
The couple are yet to go public with their new romance but did little to hide their affections for one another as they walked down the street together.
The sighting comes months after Bill was spotted passionately kissing Alex in a Melbourne park just 24-hours after filming Bachelor In Paradise's season finale.
The pair appeared to have confirmed they'd left Paradise together but then had a rather ugly split.
"Things have turned nasty and Alex is certainly keen to tell her side of the story, but she is still under a gag order for the show so she can’t say a word," they told us in an exclusive interview.
"She is devastated. After it didn’t work out with Richie [Strahan], she got engaged to Maegan [Luxa] and then they broke up and now this. It’s like she is cursed and it's all been so public too".
The source continued to add that Bill, who'd didn't find love with Ali Oetjen on the recent season of The Bachelorette, didn't want to come across like the bad guy and was 'ready to defend himself'.
Well, it looks like Bill might've found his happy ever after outside of Paradise and away from Alex Nation!
