Vanessa controversially dated Jessika's brother Rhyce Power before entering Love Island.
"She slagged me off on social media and when the promo for Love Island came out, I thought, 'oh no, that's why the social-climbing has been happening,'" Jessika revealed. "She said a lot of things about me so why not say it on air."
Jess hasn't ever approved of Vanessa, admitting that she told her brother from day one that "she's trouble" and he "needed to get rid of her".
Yikes.
It doesn't help that Vanessa actually slept with Jessika's ex-boyfriend Dan Webb from MAFS.
You can't make this stuff up.
"She dated my brother and then she went to Dan and one of my other ex-boyfriends," Jess continued, angrily. "They were only together for a few months but then she went to my ex Stephen. I was confused and shocked."
So, will Jess make it on Love Island?
Potentially!
Channel Nine recently announced a call out for people to join the show.
“If you've seen the Season 2 Islanders and already have your eye on someone then it's the perfect time to apply — there could be a spot in the Villa that only you can fill.”
“If you are sexy, young and single, aged 18-35, and are warm, honest, open and truly looking for love, then follow the link to apply for Love Island Australia."
Well, a blonde bombshell who has a knack for good ratings with a mission of revenge is the perfect contender!
Maybe she will nab Vaness's partner Matthew Zukowski as payback.
