Shocked, the boys asked if that meant Nic cheated on his wife.
"I'll say yes. It is a yes."
Adding, "He's probably cheated with loads of girls on MAFS. They just don't show it."
How does he know that Nic did the dirty?
"I heard about it. The producers told me about the cheating."
Ivan believes the cheating will be unveiled during the finale...
Which would back up Martha's theory that there is a secret clip lurking that will RUIN the finale.
As for Ivan's portrayal on the series: "The producers made me a villain. Before we shoot, they'd pulled me aside, they told me to lay into him."
"Nic and I got along after the wedding. But at the end of the day I got used to make the show more interesting."
As for Nic, he has some rather kind words about his current wife.
"Ivan's just a protective brother," Nic told 9Honey Celebrity.
"There's nothing wrong with that. And it's good to see. It's him being a really good older brother. And yeah, I respect that. And I respect their family so much."
He added: "Cyrell is one of the most generous people I've ever met honestly. It's crazy how much she just puts all of her friends and family and me first. And that's why her brother is so protective."
