Jessika has since responded to the claims.
"I didn't cheat on Nick. I spent the entire night with Tamara," the 27-year-old exclusively revealed to New Idea.
"Nick and I had been on the rocks the entire time and I decided to call time on our relationship after constant verbal fights with him," she continued.
"As everyone knows, Nick and I split in Bali and in true Nick Furphy fashion he's chasing another article."
The couple called it quits in September this year, after engaging in an explosive argument that shocked airport goers in Bali.
Jessika opened up about their split in an Instagram Q&A a week after they broke up.
The 27-year-old revealed she held no hostility towards her ex and claimed the relationship ended due to the "the pressure".
"Basically what happened was I just felt like the pressure of the relationship just caused us to argue a little bit here and there and more often."
Jess continued: "Nick and I started off our relationship because we had really good banter and we got along really well."
"I just said to him 'Don't you feel it as well? That we've been fighting a lot. I don't want us to hate one another and I don't want us to not have a friendship down the track.'"
Jess ended by wishing her ex well: "So it has ended. We have been civil to one another we haven't been nasty. It's not like we ended on bad terms, and I really do wish him the best for the future."
