A TV insider told MailOnline: ‘Whitney and Matt truly shocked the other members of the cast by cheating on their partners – not only because of the hurt it caused but the circumstances too.

‘The pairs had gone away to a couples retreat and were there to focus on their relationships, but Whitney and Matt had other ideas.

Whitney and Duka married in the show’s first episode, but their relationship was doomed from the start.

Personal assistant Whitney was on the hunt for a ‘massive brick house of a man’ but described her husband Duka as a ‘shed.’

She was met by criticism from viewers after she failed to give Duka a chance, even confessing at the altar that she was tempted to ‘run.’

Whitney said: ‘I’m hoping when I walk down the aisle I see a massive brick house of a man, he’s got to be tall, have a thick, luscious beard, I’m not going to settle for anything less than perfect…

‘I wanted a man to tower over me like massive, like a brick house, compared to a house maybe he’s like a shed.’

Duka, who moved to the UK aged 10 after fleeing the former Yugoslavia with his family, said he signed up for the show in the hope of finding a relationship that lived up to his parents’ marriage, who he said have something ‘special.’

However, Whitney entered the process after losing her mum in a devastating car accident and admitted she wouldn’t have put herself forward had it not been for her untimely loss.

Whitney said: ‘My mum passed away. She was driving home from work and a man drove into her. I really miss her. I want to say she’s my best friend. I don’t think I would have done this before my mum but why not? Life is so short, just jump right in there.’

She also explained that her grief doesn’t get any easier and if she was still here, it would have been her mum to walk her down the aisle.

Whitney continued: ‘It would definitely be mum to walk me down the aisle because she’s the one who… I am who I am because of her.

‘I’ve got a picture of my mum at the venue because she’s my heart, I wanted her to be part of the ceremony. It’s just s***, it just doesn’t get better. I feel like my mum is going to be here today in spirit, looking down on me.’

Gemma married Matt midway through the series and believed she had found The One.

After admitting that men are ‘intimidated’ by her tattoos and the fact she owns a hairdressing business, she thought she met her match in Matt, who’s also covered in ink and runs a barber.

But their romance became strained when Gemma expressed her sexual desires towards Matt and made comments he deemed inappropriate about sex at their wedding.   

During the couple’s honeymoon in Portugal, Matt revealed that he was close to quitting the show over Gemma’s forward remarks.

He said: ‘For me personally in a nice restaurant and stuff, it’s too much for me. It makes me feel uncomfortable.

‘I’ll be straight with you last night I was done – I had enough.’
