It was the unity of two reality shows as the three girls partied together at popular London nightspot Mahiki.
The girls looked glam as they chatted over drinks on the sofa. While Rosie kept it sophisticated in a monochrome dress, Jasmin added a splash of colour in a fitted purple lace dress.
Meanwhile Abi - who was pictured sharing a kiss in bed with co-star James 'Diags' Bennewith this week - wore a loose printed gown.
But it wasn't a girls-only event, as Abi and Jasmin were joined by their co-stars James Lock and Daniel Osborne.
The TOWIE gang had attended the launch of Oasis' new new Mango Medley flavour drink at the London Eye, where they played popular party game 'Spin the Bottle' with fans.
It seemed to be an eventful night though, as James, who dressed in a crisp navy blue shirt and stone trousers, took to the stage to perform a bit of karaoke.
Abi posted a photo of James singing on the mic, and he definitely looked to be in his element!
Abi said: "Everyone in the house @JamesLockie86 hahaha loving life on the karaoke." While James added: "Me giving it the Hokey Cokey on the old karaoke lastnight!!! Haha..."
The morning after the night before seemed to have taken its toll on Rosie though, after she tweeted, "Hangover cure heaven. Truffle salt and eggs."
