Married at First Sight's Bec and Danny's marriage blows up over sexy other woman: 'Do you think you are David Beckham?'

Thursday night's episode of Married At First Sight saw Bec and Danny's honeymoon in Fiji continue to deteriorate, with insecurity and mistrust coming to a head over dinner.

Earlier in the episode, the couple revisited their first night together.

Bec said she believed the intimacy had gone well, while Danny later admitted he felt the experience was 'average' and that he was not yet feeling a strong sexual connection. 

The admission clearly upset Bec, and Danny insisted he wanted to stay in the experiment to work through the lack of chemistry.

The tension carried into the evening, where what was intended to be a romantic dinner quickly became an argument. 

Bec accused Danny of repeatedly staring at another woman she claimed had been around the resort throughout the day - running past them earlier and appearing again near the restaurant. 

'Did you want a triple-take on the girl you've been staring at all day again?' Bec asked, 

Shocked, Danny replied: 'I've not even seen that girl … I don't even know what to say to that.' 

Rolling her eyes, Bec shot back: 'I'm over it. The girl that just ran past has been in your eye line all day. 'You watched her run past this morning, you watched her at breakfast. [Do a] Triple-take then.'

Danny insisted that he wasn't looking at other women, adding: 'I don't even know the girl you're talking about - that's crazy.'

'Oh! OK, I'm crazy,' scoffed Bec. 

Attempting to calm her down, Danny assured her: 'No, I'm not calling you crazy. I'm just saying, you're making me scared to look anywhere'.

'Oh, f**k off! F**k! Off!' Bec exclaimed, getting up and storming towards the bathroom.

While walking away, she vented her frustration to producers, questioning Danny's behaviour and his reaction to being confronted. 

'I'm over it. You're not into me. I don't wanna sit here and pretend we're having a romantic dinner… every time that f**king girl walks past… you've been staring at her all day,' she vented to producers. 

'You just took a triple-take in front of me as she ran past. I'm over it. You're not into me, that's fine. Let's walk away.' 

Danny, left alone at the table, maintained that he had not been staring at anyone and said he felt unfairly accused. 

When Bec later returned, producers introduced the 'Sledge Box' in an attempt to prompt honest discussion. 

Asked to name each other's most annoying traits, Bec again pointed to her belief that Danny had been looking at another woman.

Losing his patience, Danny replied: 'You're most annoying trait is that you make up that I look at imaginary women. It's disrespectful. I'm respectful to you. I don't make up lies about you. Please don't do it anymore.' 

Danny admitted there was 'not too much' at this stage but reiterated his intention to keep trying.

Despite this, the issue of the unidentified woman resurfaced almost immediately. 

Bec again accused Danny of looking elsewhere, before leaving the dinner for a second time.

'Who do you think you are? David Beckham? Do you think you're David Beckham?' she ranted while storming out of the restaurant. 

'He obviously thinks I'm absolutely hideous. And then he's angry at ME for calling him out for looking at another woman all day?!'
