It’s the final relationship test that’s been touted by expert John Aiken as “sickening” – and it appears it may have got the best of Carina Mirabile and Paul Antoine. The couple were spotted entering the very last dinner party separately.

While we hear the “Final Test” – in which participants are offered the chance to go on a date with a person outside of their marriage – seriously tests all of the couples, it’s only Carina, 31, and Paul, 30, who then attend the dinner party separately after a shocking turn of events that could drive the ultimate wedge between them.

“With Carina and Paul, you can never really tell if they’re solid or not,” shares castmate Awhina.

“A lot of the time, they put on a brave face. There were moments in the experiment, like when we did the wife swap and Paul addressed the concerns he’s got in his relationship, where it was like, ‘Well, this is all news to me!’ So they do look really strong, but at the end of the day, I could never really tell.”

Wardrobe blowout?

It costs good money to look as chic as Carina! The glamorous digital marketing manager from Perth reveals she dropped a whopping $30,000 on designer threads. She also splurged on a celebrity hair and makeup artist in order to look her sparkling best for MAFS! “I’ve always wanted to be outside the box,” Carina explains.
