In an explosive moment on tonight's show, Lacey is seen in tears as she comes to terms with the break up of her relationship with Nathan.
The Married at First Sight UK: Reunion Special airs tonight at 9pm on E4 or stream on Channel 4.
The Sun can exclusively reveal that Hannah is dating the newly single Paul Liba.
A source said: "They've been secretly sneaking out on dates for a while and wanted to keep things under wraps but it all came out at the reunion filming.
"Nothing stays secret in the world of MAFS because everyone knows everyone."
TV fans have been less than impressed with Hannah's behaviour so far – will that change tonight?
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."
