The photos, which were obtained by The Wash, two of Becky's suitors Adrian Baena, 26, and Shannon Karaka, 30, enjoying a boys' trip to Byron Bay with fellow evictees Harry James and Jake Ricciardo.
The fact the group was hanging out together proves they don't win as the winner of the show very rarely hangs out with the rest of the boys.
The Wash reports Adrian and Shannon "appeared ‘very much single’ while out partying and having fun".
An onlooker told the publication they'd seen the boys at a hostel bar and then down by the beach, "I first saw them in a hostel talking to some girls and none of them looked like Becky."
"Shannon is here too but I didn’t catch him on the pic. They were chatting with random girls I think."
The source added that Adrian "didn't care" who recognised him and was "giving off single vibes" on the trip.
This would mean that Becky's final two are Sam Vescio, 35, and Pete Mann, 34.
Pete is the favourite to win according to bookies, however, the pair had a frank chat on the show last week about how they would make their relationship work given they live in different states.
Pete is currently based in Adelaide, while Becky lives in Newcastle.
"If we did leave this together, how do you think that would work? 'Cause, like, you're in Adelaide and you've got a business, too, and that's huge," Becky asked.
Pete then shared why Adelaide is so important to him, "My family, they're in Adelaide now - my brother and my parents. And my youngest brother, just over two years ago, had a brain injury and it was really serious - like, it was life-or-death stuff."
"He's still recovering from that. And part of my work mission in many ways is to build up my business to a stage where I don't have to work and, if it's needed, I can step in for mum and dad and look after Luke."
He continued, "There are still some things that we need to work out around moving and who lives where and how that all works.
"But I believe that love conquers all. If the feeling is strong enough and the emotions are real, we'll make it work."
