However, Kristina admits there was one former Bachelor who "definitely" would've been more her type than the Survivor star - astrophysicist, Dr Matt Agnew.
"I’m also doing my PhD so I feel like we would have had a lot to talk about," she reveals, adding that Matt's was the only season of The Bachelor that she'd watched.
"I was actually approached to apply but then I watched the last season and I really liked it and Dr Matt Agnew and thought ‘Hey this could be for me’ so I proceeded with it."
Whilst her fellow eliminee Rosemary burst into tears after Locky ended things, Kristina was more sad to say goodbye to friends Areeba and Juliette who she says she was the closest to in the mansion.
"It was like we were breaking up again and we were reliving that all over again," Kristina said, adding that the three friends watched the episode together from different states.
However, the former contestant says she never saw herself, Juliette and Areeba as villains.
"I felt that we were upfront and honest – we were never nice to someone’s face and then bitched about them behind their backs like some of the other girls. I’m really happy with how we were portrayed, I thought we were very loyal friends to each other," she says.
"Everyone’s been really positive saying ‘I love the three of you’ or ‘I love the four of you’ when Kaitlyn joined. I haven’t got one bad message."
Kristina also shared an update on how Areeba is dealing with backlash from her haters online, adding that she's getting a lot of love from fans too.
"I think her messages are blowing up the most – the amount of love she’s getting is definitely offsetting the hate," she explains.
"She’s not paying attention to the hate, she’s very thick-skinned and honestly we don’t care. We don’t bring attention to things that aren’t going to serve us. If you’re going to be out there, you know what’s going to come for you and she was prepared for it and she’s handling it so well."
One contestant Kristina reckons is being portrayed correctly, in her eyes at least, is Roxi Kenny who unleashed on contestant Kaitlyn during Thursday night's cocktail party.
When asked if viewers are seeing the same Roxi that was in the mansion, Kristina replied: "Well that’s what I saw of her - that is accurate of how I saw her. I was never close to her so I never saw a different side to her but that’s how I saw her in my experience," adding that her final cocktail party was "crazy."
"I couldn’t relate to everyone complaining about small inconveniences. By then I was over the drama but it was pretty funny to see Kaitlyn finally fight back at Roxi – that was quite enjoyable to watch."
As for who she thinks is going to win? One name stands out above the rest.
"I never was on any of the single dates but watching it back it does seem like he and Irena have a genuine connection."
