It's not the first time a Married at First Sight expert has cheated with one of the show's contestants.
In fact, it resulted in an engagement on the American show.
WATCH: This is the moment that ended everything for Jess.
The blonde beauty is now facing a brand new cheating rumour.
Off the back of rumours that she hooked up with Telv Williams, Jessika has taken to Instagram yet again to defend her honour.
On Tuesday night, Jess took to her Instagram story, commenting, "I am ABSOLUTELY killing it."
Her remarks were in response to an allegation made by publication Double Bay Today that she had a dalliance with resident MAFS expert John Aiken.
They claim she exclusively spoke to them.
“I’m very sexually attracted to John,” the 27-year-old told Double Bay Today.
“To be honest, I have been into him since the start of the show.”
They claim John - who is happily married - has been in Jessika’s hometown of Perth for the last seven days.
“We’re exploring where this relationship can take us,” the article claims the MAFS expert said to them. “I know it’s unprofessional for me to date someone from the show. But love is love.”
Before you all lose your minds over probably the biggest MAFS scandal of all time...
Double Bay Today is a satire news site.
Jess clearly has taken the joke in her stride.
In another Instagram post, she gave them material on who she has her eyes on next.
She shared what looks like a photoshopped fan-made post which says, "Just in: Jess from MAFS is now dating Egg-boy."
The MAFS bride captioned it, "UPGRADE!"
