Keeping it local, the girls decided to unwind for a few drinks at Fifteen York Hill in Loughton, Essex, on Sunday night (25 August) and they soon kicked off the party with plenty of dancing and cocktails.
Sam showed off her glowing tan in a fitted black playsuit that she teamed with white heels, while her sister Bille wore a patterned animal jumpsuit.
Reality star Ferne, who showed off her wild side in a slinky tiger print green and black midi dress, let her hair down despite having had a tough couple of weeks following rumours that her boyfriend Charlie Sims had cheated.
Billi, who left the ITV2 reality show in May to launch her own Bikram Yoga studio, added a splash of colour in a coral mini dress.
Ferne and Sam also showed off their glam outfits in several photos, as they posed with friends before their night out on the town.
Posting a photo of the night's festivities to Twitter, Billi said: "Fun night at @FifteenYorkHill with @SamanthaFaiers @BillieFaiers @fernemccann @JennaBowe."
It looked to be a full on TOWIE reunion too, as former star Lauren Goodger also joined in on the fun after being persuaded by Ferne over Twitter!
Before a night of partying, Ferne had also told her Twitter followers: "Loving my little life right about now...be grateful for what you have. Appreciate the good...and be positive."
