Made In Chelsea EXCLUSIVE FIRST LOOK: Zara McDermott enrages Jamie Laing as she claims to have cheated on Sam Thompson because their romance was ‘hanging by a thread’

Zara McDermott will finally own up to cheating on Sam Thompson during Monday night’s Made In Chelsea.

In an explosive clip exclusive to MailOnline, the beauty, 23, breaks down in tears as she tells Sam’s best friend Jamie about her indiscretion – leaving him outraged.

Sitting at a dinner, Zara says through tears: ‘I did something really bad around a year ago. I slept with someone!’

Jamie, alongside girlfriend Habbs, are left aghast, with Jamie left stuttering: ‘That’s not very sweet!’

Zara goes on: ‘When it happened I genuinely thought that me and Sam were going to break up inevitably. I just thought we were hanging on by a tiny thread and we’re going to break up.

‘Then he turned around and said he wanted to make it work with me.’ 

Jamie says that she shouldn’t make excuses, with Zara insisting she isn’t, and that she is explaining why it’s only coming out now.

‘Are you are Sam still together?’ Habbs asks, with Zara replying somberly: ‘Yeah but I don’t think for much longer!’

Jamie says: ‘I’m not going to be the best person in this situation ladies. I’m probably going to make things worse.

‘Obviously my loyalties are with Sam, so I think I better just leave you to it.

At this, Jamie leaves the table.

The episode will air on Monday night at 9PM on E4, and will see the drama play out in full.
