MAFS Final Vows: Betrayal Sparks Explosive Feud!

Each year, MAFS's Final Vows bring the expected mix of happiness and heartbreak, but rarely are viewers hit with a blindside better suited to .

That's exactly what went down with Bec Zacharia and Danny Hewitt.

Bec walked in believing they were about to start a life together, and walked out so shattered that crew members were genuinely worried for her.

'Her world came crashing down,' an insider told me. 'There was nothing anyone could do about it.'

Bec also admitted in an interview with the Daily Mail that the break-up left her feeling 'like an idiot… and not just an idiot - an idiot on a public scale.'

Sources on set said Bec was visibly broken after Danny broke up with her.

'I've never seen anything like it,' one admitted. 'She genuinely believed they were walking out of the Final Vows together.'

The reason why the outcome was so confronting for Bec is because she genuinely believed it marked the beginning of their relationship, not the end.

In the weeks leading up to Final Vows, she had been telling her inner circle that Danny was developing strong feelings for her.

She believed that Danny was falling in love with her and was waiting for Final Vows to say those three words she had been waiting weeks to hear.

Remember: Bec had said 'I love you' first during a cringe-inducing Commitment Ceremony earlier in the season and Danny had not said it back.

'He told me he was falling in love with me… that we were going to make it work,' she told me.

'I believed his words… but his words were always off-camera.'

But there's a problem here: I checked with other cast members and production insiders to see if anyone could corroborate this. Nobody could.
