It has been revealed that Jessika Power attempted to seduce another woman's husband earlier in the season: Nic Jovanovic.
After the truth emerged (as it usually does) Daniel was so engulfed with rage by the betrayal he tried to end his relationship with Jessika then and there.
Apparently, according to Daily Mail Australia, poor Dan Webb doesn’t even know the half of it.
During Sunday night's reunion, the whole cast will watch footage of Jessika telling Nic she is 'sexually attracted' to him what they most likely won’t be told is how the pair also allegedly hooked up in an elevator during the season.
Rumour has it that Nic and Jessika got physical during the show, but the full extent of their hook-up has never been exposed.
Martha Kalifatidis scandalously stated that Nic had rubbed Jessika's leg provocatively under the table during a dinner party.
Of course, he denied it was sexual and insisted it was simply a ‘friendly gesture’.
The 'secret elevator hook-up' rumor mill is real.
The hook up was never discussed on the program and apparently took place away from the cameras.
From the video, we can definitely tell something went down between the two…
The rumor comes after Jessika told News.com.au that she and Dan briefly split at the reunion dinner party after he watched weeks-old footage of her propositioning Nic.
'He'd seen the video of me saying I was sexually attracted to Nic, and his ego was hurt,' she said. 'He went, "Obviously we're not together now".
'And I said, "Whatever. I never got what I wanted out of this relationship anyway". I was being a brat!'
However, the 27-year-old confirmed that she and Dan reconciled just two days later and their relationship is now in a much better place.
Jessika, who was originally paired with Mick Gould on MAFS, had secretly propositioned Nic during one of the weekly dinner parties earlier in the season.
However, Nic turned her down and said he wanted to stay with his wife Cyrell Paule and work on their marriage instead.
It was only after her rejection that Jessika turned towards Daniel.
The pair then started a full-on affair, before dumping both their spouses at the commitment ceremony and re-entering the experiment as a new couple.
While Jessika's flirtation with Nic was not revealed to the group during the main part of the experiment, it will finally be exposed at the reunion dinner party.
A newly-released trailer for the MAFS reunion hints that all hell breaks loose when Jessika and Nic's secret is finally revealed.
In an extended promo, the relationship experts play back the shocking footage of Jessika propositioning Nic in front of the entire group - leaving Dan stunned.
'I honestly feel like I've just been played,' he says after watching the video of Jessika brazenly admitting she is 'sexually attracted' to Nic.
