The trio swapped Essex for the south of France to represent the ITV2 reality show for TV production company, All3Media's 10th birthday, and have wasted no time in celebrating since arriving last night (7 October).
Tweeting a photo of the trio on a boat, Sam said: "Pre drinks in Cannes marina on a boat having a amazing time !! Next stop party at the majestic."
Arg, who dressed smartly in a black suit, was all smiles as he stood in between Sam and Gemma, who looked stunning in glamorous frocks. Arg even treated the girls to dinner!
The trio then headed to Majestic Barriere hotel for a party, and were perhaps taken aback to see their faces projected onto the building! Sam, who has been an original on TOWIE since it started in 2010, added: "Proud to be part of such an amazing show #cannes."
Apart from rubbing shoulders with industry professionals, it turns out that Arg has made a new friend in comedian and Little Britain star Matt Lucas!
The two clearly had loads in common and later posed for a quick photo. Arg said: "Having a good chat with my new friend and nice gentleman @realmattlucas would love to be in Les Mis one day! #Cannes."
The new series of TOWIE kicked off on Sunday (6 October) with the first of its two-part Vegas special. The second part continues on Wednesday 9 October at 10pm on ITV2.
