Sassi Simmonds and Darren Quirk were on the track for a real fresh start in last week’s episode of Teen Mom UK, with the pair getting a new home and the mumheading to anger management to work on her temper.

However, in this week’s brand new episode, the couple hit a bit of a stumbling block during a romantic getaway to Amsterdam, as they end up having a huge argument after Sassi jokes about Darren proposing.

Sassi and Darren are at loggerheads in this first look at Wednesday’s new episode:

In this sneak peek look at the drama, things initially look to be going well between the couple as they cosy up together during a rainy tour of the city.

However, things quickly take an awkward turn when Sassi jokes about Darren proposing to her, with the mum-of-one saying: “This would be the perfect time for you to pop ‘would you marry me?’. In the rain, in Amsterdam, on the canal.”

With no response from Darren, Sassi continues: “I’m only joking with you Darren don’t worry, I don’t expect you to you know. But I do have a ring here if you want to just do a fake one now.

“No I’m only joking… Me and you are really really opposites.”

Giving a brutal response back, Darren tells her: “That’s why we can’t get married.”

Confused by what’s just been said, Sassi replies: “Oh. Okay then. Great. That’s why we can’t get married? Well, to be honest, I’m not really sure if I want to get married myself to be honest.”

As Darren tells her to “stop gassing mate,” she adds: “I don’t think we’re ready to get married.”

Things go from bad to worse as Darren tells Sassi to “shut up,” explaining: “I’m not the one who wants to get married, you’re the one who drills it in my head.”

Their argument continues, with Sassi telling Darren: “You’re the one getting angry yet again,” as he continues to tell her to “shut up”: “I’ll tell you a thousand times, shut up.”

After Darren eventually storms off away from their tour, Sassi reveals: “I think it’s Darren that needs anger management, not me.”

Yikes.
