Hannah had a disastrous time on MAFS, joining the show as a late bride and tying the knot with Stephen Nolson.
But despite initially seeming like a good fit, the pair's relationship dissolved quickly – and it was only made worse when the girls of the group didn't get along with her.
As the pair sit down to chat, Hannah is given the room to speak and says: "I just think the way I was treated was pretty s**t. There was moments where I do feel like you were going out of your way to kind of disrespect me and belittle me and try and make me feel like s**t.
"I genuinely don't think I flirted with Alex, I think we were just building a bit of a friendship."
If you're just joining us, here is a quick recap to get you up to speed:
All eyes are expected to be on Holly and Hannah who come face to face tonight in the show.
It's fair to say the pair never saw eye-to-eye, with Holly, pictured below, right, accusing Hannah of flirting during the experiment.
On tonight's show Hannah tells Holly of her take on events – while Holly responds, with things taking an emotional turn as she opens up about feeling insecure.
"I have been through some treacherous s**t in my life, Hannah," she begins. "It's not even a personal thing but you did relate a lot to my insecurities where a woman came in and took away my relationship."
