Mia Boardman and Manley Geddes have faced some seriously tough times on this series of Teen Mom UK, with the pair going through several rough arguments before calling time on their relationship.

Sadly though, it seems the trouble doesn’t stop there for lovely mum Mia, as in the series finale, there’s one more thing on her mind that she’s desperate to sort out.

That thing being finding out why Manley’s ex Erin Corrigan has apparently been going to Manley’s mum Maggie’s house for the past couple of weeks.

WATCH MIA COME FACE TO FACE WITH ERIN IN THIS SNEAK PEEK VIDEO:

In this sneak peek look at the upcoming dramz, we see Mia heading off to confront Erin, who has daughter Aalayah with Manley, about EXACTLY what’s been going on.

Speaking in a voiceover, Mia admits: “Now Marliya’s party is out of the way, there’s something else on my mind I need to sort out.

“Manley’s ex Erin is spending more time at his place and I need to know if she’s trying to get back with him. It’s time we had this out face to face, so Manley’s mum has arranged a meeting in town. She’s still desperate for us to be friends.”

In the cafe, Maggie starts the conversation by telling the girls how nice it would be if they at least got on, explaining that although they don’t have to be friends, they should try and be civil.

She tells them: “At the end of the day, you’re both in the same situation. You’ve both got children to Manley, my two little granddaughters and I love them two little girls so much.

“Nobody’s saying you have to be friends, obviously not, but social to each other, it would be nice and it’s nice for them. It’s nice for them to know their mums don’t hate each other. You don’t want that with your kids, they love each other so much.”

The three then discuss just how alike Aalayah and Mia’s daughter Marliya are, before Mia finally tells Erin exactly what’s been on her mind: “Since me and Manley broke up obviously you’ve gone round Maggie’s loads when you never went round before.”

In response, Erin explains: “What the past two weeks? Manley had Aalayah for me and I didn't wanna not see her for two weeks so I went up and took her out.”

Mia continues: “I just thought it’s just since me and Manley have obviously broken up, I heard that you were like going round there so I just thought ‘oh how come she never went round before’.”

Erin then explains that she didn’t go round before because Mia was there and ‘didn’t want (Erin) coming round’, before Marliya’s mum adds: “Me and Manley moved out six months ago so that’s why I was just wondering like why in the last six months you haven’t been round but you’ve been round loads the last couple of weeks.”

Telling Mia that she’s got nothing to worry about, Erin says: “Obviously it does look bad you thinking I’m going round there but it’s nothing like that (…) Me going round is nothing to do with Manley.”

Despite their meeting going well and Erin seemingly denying anything is going on with her and Manley, Mia admits that she’s still not convinced that she knows what’s really on Erin’s mind.

Speaking back at home, she admits: “I wanna know, ‘do you wanna get back with Manley?’, that’s what I should’ve asked her. But I didn’t want to make it too awkward, it wasnice of her to even come meet me in the first place really, as hard as it is for me to admit that.

“She’s quite hard to work out, so I don’t really know what she was actually thinking or how she was meant to react. When you don’t know someone, it’s quite hard to actually know what they’re thinking. It was good for us to have the chat but I think it will always remain a bit awkward.”
