The reality TV stars will be jetting off to Sin City very soon to film two special episodes for the hit ITV2 series, along with the rest of the TOWIE cast including Lucy Mecklenburgh, Sam Faiers, Lauren Pope and James 'Arg' Argent.
And although all of the gang are eager to get over to the States, it looks like Chloe and cousin Joey are the most excited.
Yesterday (9 September), the two had a little competition on Instagram to see which of them could look more "gassed" about their upcoming holiday.
Chloe posted a cute snap of herself in a baggy T-shirt and sat on her living room floor with her hands in the air as though she was dancing. She wrote: "So #GASSED for Vegas #VegasGassedFace beat that @JoeyEssex_"
She also added another picture of herself with a huge smile on her face, along with the caption: "#Excited #Vegas #Gassed #woo"
Can we just point out how much we love Chloe's natural and laid-back look here too?!
However, it seems cousin Joey might have just trumped her, as he proved his enthusiasm by posting a photo of himself wearing a Las Vegas T-shirt.
Joey wrote: "Packing for VEGAS already with my Vegas T-Shirt on!!! #ExcitedUnited #Gassed #Vegas3rdTimeLucky #VegasIsLife #WeLoveVegas #PoolPartyKiddos"
The Essex native then went one step further by uploading a short video clip of himself and co-star Tom Pearce excitedly shouting "Vegas Baby".
Not only has Joey prepared for the trip by buying an appropriate T-shirt, he has also purchased a black cap with a crown logo on the front and the word 'KING' written across it.
The hat is apparently meant to represent his self appointed title as 'King of Vegas', which he states in the Instagram video.
Since Joey has gone to the effort of buying a customised cap, making a video and giving himself a nickname, we might have to agree that in this case he is the most enthusiastic TOWIE star.
Joey's ex fiancée Sam Faiers has been sharing her excitement about heading to Vegas with her Twitter fans too.
Last week she tweeted: "Ohhhh yeah !!! VEGAS this month!! Who's excited! #towie it's going to be amazing!! "
We can't wait to watch all the drama unfold.
