Teen Mom UK’s Shannon Wise has had a rocky path with boyfriend Charlie over the course of the series, with the pair trying to patch up their relationship and work on a schedule for looking after son Theodore.

In this week’s episode, the couple head off on a family holiday to Majorca to continue building on their relationship – only to have their sunny vacation end in a huge row over some rumours surrounding Shannon’s pregnancy.

Watch Shannon throw a drink over Charlie as they row about rumours in this sneak peek video:

In this first look at the new episode, we see Shannon and Charlie head out to the balcony to talk about a conversation they had yesterday, where Charlie “accused Shannon of getting pregnant on purpose.”

Trying to get to the bottom of his comments, the mum-of-one, who admits the previous conversation made her “really upset” asks him: “You said that it was basically my fault that I got pregnant and that we weren’t together when I was pregnant.”

Telling her his words “probably came out wrong,” Charlie explains: “You’ve got to understand, when all that thing came about when, remember your best friend told me that you told her that you told her that you’re not going to take the pill because you want to have a baby.”

Shannon admits she does get it from his point of view, but asks: “Why would I do that?”

He replies: “I’m not saying I believe her. That’s your best pal, where’s it come from?”

Getting more annoyed, Shannon says: “I don’t know, Charlie. It’s just the fact you’re bringing this up all the time yeah?”

Having to deny again that she didn’t get pregnant on purpose, Shannon reaches boiling point when Charlie tells her to “answer to (the rumours),” throwing a drink and other items over him and storming off.

Away from the balcony, Shannon explains: “I’m absolutely gobsmacked at what he has said to me. Now it’s just going to be horrible between me and Charlie tonight.”

The couple later come together and try and solve the issue once again, with Shannon telling Charlie: “Why do I need to answer for what someone has said to you? That is not my problem.”

Can the couple sort things out?
