The super loved up couple were pictured dancing and kissing during a final night of partying at Plaza beach, before heading back to Essex today.
Ah! We'll miss our daily Marbs pictures!
After a minor disagreement at the start of filming in Spain, they've been ridiculously, blissfully happy in every photo we've seen, holding hands, kissing and generally looking super content.
So we'll be seeing a very different Lydia and Arg this series!
Fans of the show will remember they got back together again on the finale of the last series, after Arg spent the whole series trying to win back his childhood sweetheart's affections. Eventually, he did, by pledging his love, saying he had changed and presenting her with a list of the women he'd cheated on her with in the past.
Before flying out to Marbs, the couple took part in a photoshoot for Reveal, where they both gushed about how in love they are.
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."
