The Essex girl - who is sister to Charlie Sims and Chloe Sims - appears in the ITV2 series for the first time ever. Exciting!
In her first ever scene, Charlie talks to his two sisters about his feelings towards girlfriend, Ferne McCann, so no doubt tension will be in the air...
The couple split up in the last series after various cheating rumours, but fans watched them get back together in the Marbella special.
However, their happiness didn't last long and the TOWIE curse struck again– as a video emerged of Ferne getting cosy with another boy at a Vegas pool party.
We then saw Chloe and Ferne row over the drama and, despite Ferne and Charlie getting back together, things have still been awkward between the two Essex girls!
Charlie and Elliot Wright also go boxing on the episode, leaving Chloe and Ferne alone to set up Charlie's delicatessen – awkward! Will the pair kiss and make up or will things still remain tense?!
Elsewhere in TOWIE-land, Jess breaks down in front of Gemma Collins and Billie Faiers over moving out on her own, instead of living with boyfriend Ricky Rayment.
The gorgeous couple have been so loved up lately, we wonder if they should be shacking up together!
