"That song (Y2K, bbno$ - La La La) is from 2019," he told New Idea, referring to the track Jessika and Joely were singing to before they smooched on the back of a motorbike.
The song was indeed released in 2019, back in June.
"Her teeth had been done and she was wearing the same clothes she wore the same f***ing day. That guy didn't even have a tattoo on his cheek in 2018. Come on now. All the evidence is there. It's the way she's been brought up, she's a compulsive liar and she hasn't learnt how to be honest with herself and those around her."
While some fans of the former couple believed Nick's Instagram post was unnecessary— with one arguing he and Jessika should've dealt with the matter privately— the reality star doesn't regret exposing her on a public platform.
"I have been amicable with her the whole time and we've been on good terms but when I saw that, it was a bit of a kick in the guts. She did f***ing lie to me. I had to pull her up and I thought she could probably learn from this. It was 3 am in the morning when I saw it and I couldn't get back to sleep for two hours.
He continued: "I don't hate her, just a bit disappointed. I am not a bully and someone needs to take a stand and say this is wrong, what you're doing. Bad behaviour needs to be pulled up."
Although Nick's quotes muddy the waters‚ with many unsure who to believe, rumours have long been swirling Jessika cheated on her boyfriend while they were vacationing in Indonesia.
In fact, Nick says he confronted the Instagram influencer about the issue at the time.
"A friend of mine from Bali gave me a heads up. I asked her about it and she cracked the sh*ts saying, 'Why wouldn't you believe me?' She was very defensive. I did believe her but in the back of my head, I knew something wasn't right. There is a right and a wrong way to end a relationship. Just be honest and don't be a sh*t person. I would have more respect for her if she was real.
Despite refraining from contacting Jess before posting the video to his Instagram account, she messaged him yesterday, threatening legal action.
"She has threatened to sue me for defamation and all this sh*t but that's not going to happen. She said she's talked to her lawyers. I just said, 'I will see you in court'."
During the chat, he also dished on the infamous fight the couple shared at Ngurah Rai International Airport, hitting back at Jess who said: "I was at the airport and he was being really arrogant and rude to the waitstaff and I just screamed at him saying, 'You are no better than anyone else. You think you're something you're not and it's disgusting.' I just lost it. I was like, 'A lot of people don't like you because you are arrogant.'"
Instead, Nick says after a few drinks Jess was the one looking to fight.
"Her flight was cancelled and she was there for 12 hours. We ended up drinking red wine all day in the lounge and she was looking for an excuse to get angry," he revealed. "I said 'The world revolves around money' and she flipped her sh*t. She was probably a bit intoxicated and she was walking through the airport yelling and creating a scene. I didn't want to leave on that note."
As for where he stands with the former MAFS villain, Nick has made it very clear he has little interest in hearing her out or reconnecting.
"She's blocked. You cheat on me, you're f***ing done."
