The TOWIE girls were the first to arrive in Vegas earlier this week and they've wasted no time topping up their tans in the hot sunshine.
Lucy, Ferne and sisters Sam and Billie headed to the outside swimming pool at the plush Encore hotel before relaxing on giant waterproof beds.
Posing for a group photograph, the Essex ladies appeared to be having a great time as they bundled together while smiling and laughing.
They were all wearing sunglasses and their hair down while Ferne and Lucy - who had new extensions put in especially for the trip - pulled peace signs.
Ferne shared the picture on Twitter, along with a short Instagram video of the foursome dancing along to a pool party held at the hotel.
Alongside the video (below), she commented: "#vegas #encore #avicii amazing day."
The TOWIE cast are in Las Vegas to film a two-part special that will kick start the next series.
Yesterday, Chloe Sims made a last minute arrival in sin sity after flying out there on her own.
Chloe's daughter Madison had been poorly and it was feared she would miss out on the trip, however she has since recovered.
