Dan and Jessika's secret love affair continues to heat up on MAFS this week – and there's one viewer who's even more shocked by the cheating scandal than the rest of us: Dan's on-screen wife, Tamara.
But while Dan and Jess are yet to come clean to their partners, Tamara already has her doubts about their future as a couple.
"It won't last, mark my words," an unimpressed Tamara, 29, tells TV WEEK.
Tamara says watching Dan and Jess' romance play out on TV makes her feel "sick to the stomach".
She also says the pair should feel embarrassed over their "disgusting" and "disrespectful" behaviour.
"It's been really hard to watch it all unfold," Tamara, says. "Their behaviour speaks for itself and they should be embarrassed.
"I'm a strong enough person to know my worth and it's not something I want to be a part of."
Tamara admits she did have a gut feeling something was going on between the pair, but still thought Dan wanted to make things work.
"I didn't know it was happening so early on," she says.
"Dan would tell me how beautiful I was, but behind my back he said he wasn't able to talk to me. It was all a complete and utter lie."
Last week's explosive dinner party saw Dan, 35, and Jess, 26, grow even closer as they confessed their true feelings for each other.
Tamara believes the way Jess acted is on a par with how Ines pursued her relationship with Sam while she was still married to Bronson.
"Both have gone behind people's backs to get what they want," she explains.
"It just goes to show Jess' character and what type of person she is. She's not somebody I'd associate with in the outside world."
Married At First Sight airs Monday to Wednesday, 7:30pm, and Sunday, 7pm, on Nine.
