On Monday’s episode of Made In Chelsea, Sam was visited by his pal Reza Amiri-Garroussi who came bearing a letter from Zara.

On the break up, Reza said: ‘Got to say though after meeting her, I did feel bad for her. She’s in a bad way. It’s a s*** situation for everyone involved. But she really is upset. Legit.’

Sam then broke down while reading out the letter from Zara, which read: ‘Dear Sam, since you’ve been away I’ve been doing a lot of reflecting on a lot of things. I’ve reflected on my life and our life together and also the kind of life I want to live…

‘Before I continue with some of the things I need to say, I just want to tell you again I am sorry with my whole entire heart for what I did….

‘I’m so deeply ashamed of my actions and the way I hurt you. I was selfish, immature and stupid. There is no excuse.’

Reza then told Zara that Sam is ‘completely out,’ despite her attempts and letter to win him back to which she started crying. 

Over the weekend, Zara shared an impassioned throwback post of her and Sam kissing, which read: ‘I choose you. And I’ll choose you over and over. Without pause, without a doubt, in a heartbeat. I’ll keep choosing you’.

Zara, who dated the MIC star for around a year, didn’t tag Sam in the romantic photograph and he is yet to comment on her latest declaration of love.

The former Love Island star still follows her ex on the photo-sharing app however Sam unfollowed her after the cheating allegations came to light.

The post comes after Sam mocked the moment Zara begged for his forgiveness on TV in a now-deleted video, before later apologising for causing any offence and insisting he asked for her permission.
