Made In Chelsea new girl Mimi Bouchard gets inbetween Olivia Bentley and Fredrik Ferrier on tonight's show.
Last week the cast enjoyed the sun, sea and sand of Mauritius but there was trouble in paradise for Tiff, who started to wonder if she and Sam wanted different things out of their relationship.
Julius found himself on the receiving end of the affections of new MiC girl Daisy Robbins, but there was someone else in the party he was more interested in pursuing - Daisy's friend, Ella.
And back in Chelsea, Ryan learned that James had been talking to the boys about his new-found friendship with Louise, and decided to confront him over it.
This week, Olivia and Fredrik are the picture of love's young dream, until new girl Mimi rocks them with news of a secret flirtation.
Liv confronts Mimi over the rumours: "Question. Do you fancy my boyfriend?" and complains about her flirting with Fredrik.
Mimi responds: "Why are you worrying what I do when your boyfriend is hitting on other girls?"
Later, Mimi spills on Fredrik's apparent advances towards her, prompting Liv to snap at him: "You have a girlfriend you moron!"
Fredrik explains: "We met once and we got on, what's wrong with that, why are you being so crazy?"
Mimi adds to Liv "Why are you so insecure in your relationship?"
An unimpressed Liv responds: "If you think she's hot and you want to bang her, be my guest, but you'll be single."
Elsewhere tonight, Daisy has a secret about Sam that threatens to push Tiff and Sam's already troubled relationship to breaking point.
Meanwhile, Louise's wild night out with her party pal Alex causes Ryan to worry that this old friend is a bad influence on his reformed other half.
Made In Chelsea continues tonight on E4 at 9PM.
