The girls came to blows on more than occasion in the last series over Ferne's boyfriend and Chloe's brother Charlie Sims - and it's still unresolved.
On Sunday's episode (12 October), viewers will see Mario Falcone and Jessica Wright caught in the middle of the girls' animosity.
Returning cast member Mario is close to Ferne, and having reignited his friendship with Chloe in the last episode, he's keen for the girls not to argue.
Meanwhile, Jess' friendship with Ferne clashes with her family loyalty to cousin Elliott, who is currently loved-up with Chloe.
We'll soon see that it's not all fun in the sun, as the situation reaches a climax in Ibiza and Ferne exchanges heated words with Chloe's boyfriend Elliott.
In the last episode, Ferne and Chloe did not speak to each other, but there was tension between the pair when Ferne interrupted Chloe's conversation with Charlie in a club.
Chloe was dealing with drama of her own though, as she came face-to-face with former flame Mario, who claimed she had cut their friendship short since dating Elliott.
Chloe said she still regarded Mario as a friend, and he suggested that she joined him for lunch, which didn't go down too well with Elliott!
It didn't take long for it all to be resolved though, as the trio soon managed to settle their differences.
The drama continues in The Only Way Is Ibiza on Sunday 12th October at 10pm.
