Jonethen and Lilli went public with their relationship in September with a series of loved-up snaps and videos after a holiday in Mount Tamborine.
And it's clear things are getting serious between the two judging by the many posts each has shared of the other.
"My love," Lilli sweetly captioned a recent couple photo of herself and Jonethen.
Jonethen was matched with introvert bride Connie on the hit reality dating show and their marriage was certainly a rocky one.
Tensions famously rose when Connie unexpectedly voted to stay at one drama-filled commitment ceremony after a tumultuous week.
Jonethen later told Nova's Fitzy and Wippa that producers persuaded him to stay on the show and that he was forced to continue filming for nearly a month before being allowed to exit the experiment.
"It was maybe three or three-and-a-half weeks," he said before being asked how long he'd been actually writing "leave" at the commitment ceremony.
"They only have so much time on the show so they do pressure certain things or ask stuff like 'why aren't you guys having sex?' I kept saying to them, 'I don’t see anything in this relationship, I wanted to leave'."
At the final commitment ceremony, Connie and Jonethen called time on their romance deciding to stay friends instead. However, Connie cut off ties with Jonethen when he ditched her birthday for a paid club promotion.
"He was with Mikey, Ivan, Steve and Dave... I get it, these guys are celebrities, they're D grade celebrities," Connie told A.B and Ben on Hit105.5's Coff's Coast.
"They had this very important event to go to and they said after it was done they'd come and meet me for a drink. I thought, awesome, that'd mean the world to me. But after saying they'd come, they didn't even bother."
She added: "I thought they could take an hour after lapping up that D grade life to have a drink with a mate. They were too busy with their meet and greets and thinking they're really relevant and important."
