Ferne joins close friend Jordan Sargeant on the show, where she gets the lowdown on her pal's romance.
Sporting a printed bikini, the Essex star sips champagne with Jordan and Alex Weaver while discussing Jordan's never ending love triangle.
In a clip teasing tonight's episode, Ferne asks Jordan by the pool: "Can we talk about Jon Stretton Knowles? I think you've fallen for him a little bit."
However, despite going on a romantic date last week, Jon appears to have changed his tune with Jordan and wants to nip their fling in the bud.
It seems he's got a case of cold feet as Jordan has got "too clingy".
We soon see Jordan telling former flame Josh Ortega that she really likes him, but he says she "blew it" by going on a date with Jon.
Will there be hope for Josh and Jordan?!
Watch a preview below:
Before Life On Marbs aired, Jordan told Reveal that Ferne gave her advice ahead of the show - but she didn't take any of it on board.
"Ferne gave me advice to just be myself, don't hold anything back and to just be honest and not to hide anything... And to keep my knickers on!" Jordan told us.
"She gave me advice on my love life. I have some romance on the show, but I didn't take her advice.
"I've learnt and I've made my mistakes. Everyone has got to make their own mistakes, so I'm slowly repairing myself."
