Now, the couple seem to be getting more serious, with Konrad posting about his girlfriend on Instagram.
Konrad rose to fame on Brook Blurton’s season of The Bachelorette, before dating Abbie Chatfield.
The two had a highly publicised relationship, candidly discussing their open relationship on social media.
"I've never been upset or threatened by someone [I'm in a relationship with] sleeping with someone else. It's my kink," Abbie said in a chat with Stellar Magazine.
"I just never really valued monogamy that much. It sounds awful, but I don't really see him all that much, maybe two days a week," she revealed.
"I don't know if it's scarcity, but he's very good at communicating, and so am I."
However, the pair announced they had officially ended things earlier this year after rumours of Konrad kissing another contestant during the filming of the new series, The Challenge swirled.
Konrad revealed that he and Abbey had split the month before he started filming the season, also announcing that he identified as Pansexual.
During The Challenge, Konrad hooked up with former Bachelor contestant Megan Marx.
