The couple - who rekindled their romance last series - were pictured enjoying a group meal with co-stars including Tommy Mallet, Georgia Kousloulou, Chloe Lewis and Jake Hall on Tuesday evening (2 June).
Ahead of jetting out to Marbs, the pair posed for an exclusive Reveal photoshoot.
A seriously loved up Lydia told us: "We're really passionate, we get on so well. I've never had this with anyone else - I love him so much it aches my heart. James is the only person who gives me that feeling. I wouldn't want to be with anyone else now.
"The TOWIE curse is nerve-wracking, but I think we can beat it! I don't think anything really bad will happen."
Like all couples, however, they do have the odd argument...
A source told us that Lydia and Arg had a disagreement after arriving in Marbs over the weekend but swiftly made up and, judging from last night's pictures, are really enjoying their holiday.
We'll find out what that disagreement was when the new series of TOWIE kicks off this month on ITVBe.
