Earlier this week, a woman named Hannah told KIIS FM’s Kyle and Jackie O that Dan had kissed her on a night out two months ago.
Now, speaking to the radio hosts, MAFS star Jess has denied the allegations.
"Dan says it's not true. I just don't see him doing that," Jess said.
"People are throwing around cheating allegations on my end and on his end, and I just think, 'Why would be put ourselves through so much effort and all this emotional stress just to cheat on each other?"
The reality star also discussed the couple's incredibly awkward interview on Talking Married, which aired after the show's finale.
"We're working through a lot of things at the minute," Jess told Kyle and Jackie O.
"I feel humiliated with the way that he spoke to me on Talking Married," she added.
"I'm a little bit hurt, Dan's a little bit hurt."
Ahh, we love a cheeky swipe between former morning television co-hosts.
And the latest sass injection from none other than former Today host Lisa Wilkinson levelled at Karl Stefanovic is simply glorious.

It's been a helluva week. I'm only sorry that I never got the chance to say goodbye to you all...the incredibly supportive, engaged, opinionated, clever and wonderfully diverse audience of Today. Thank you from the bottom of my heart for all the fun years we shared, and for welcoming me into your homes each morning. It has been an absolute privilege. Lisa.xxx PS. This pic is from Karl's and my very first publicity shoot way back in May 2007. Look at us, we were babies!!
