The reality stars, who are in Vegas with their co-stars to film a two-part special for the new series, wasted no time in mixing with the locals, and went shirtless as they partied at Bare Pool at The Mirage.
And it sounds like they were partying in luxury as the venue boasts cabanas, VIP beds and luxury dipping pools! Tom said: "Chilling @BarePool party Las Vegas with the boys.... Looking... Smelling.... Being."
In another photo, Joey and Arg look to be having the time of their lives as they soak up the sun rays on a sun lounger. Captioning the snap, Joey said: "Me and the Arg ... Vegas is good. Real good."
An excited Joey later told fans on Twitter: "I can't wait for you all to see THE ONLY WAY IS VEGAS... I seriously can not wait for you to see this!!! @itv2 @OnlyWayIsEssex."
They may have only just landed, but it already sounds like chaos. Speaking about their first night in Sin City, Arg said: "In Vegas at 6:20am... @joeyessex_ is passed out @tompearce1 is crying over how much money he's lost and I'm just giggling to myself #typical."
The boys have also been entertaining their fans with numerous Instagram videos.
One in particular shows the duo embarking on some late night activities in their hotel room as they sing and dance along to Gabrielle's 1993 hit 'Dreams'!
