They joined the rest of the Essex gang out on the town but amid all their partying, the pair made sure to indulge in a cousinly catch up.
Cuddling up for a sweet photo together, Jess shared her snap to Instagram this morning, telling fans: "Me & my @elliottwright_ last night."
Just look at how tanned they both are!
In her photo, Jess and Elliott are pictured looking oh-so-bronzed and we have to say we're seriously envious of their holiday glows.
Essex beauty Jess looked gorgeous, rocking a sheer top and patterned shorts. In a bid to beat the Spanish heat she swept her long brunette locks back from her face into a loose ponytail, keeping her look oh so glam with a slick of coral lippie on her lips.
Elliott, meanwhile, looked dapper in a long-sleeved polo shirt and fans were quick to notice his evening outfit choice highlighted his buffed up bod.
The reality star had begun telling followers he was getting himself into shape for summer months back, and it seems his hard efforts haven't gone unnoticed with one user commenting: "The hulk?"
He and Jess are currently filming for TOWIE's fifteenth series out in Marbs and so far their trip overseas has been quite eventful for Elliott.
Earlier this week, Elliott was spotted kissing ex-girlfriend Chloe Sims after coming face-to-face for the first time since their split.
The pair were then snapped kissing for a SECOND time (thanks to Jess sharing a snapchat of their smooch!) and we're all dying to know if this means Chloe and Elliott are officially an item again.
So far, the couple are keeping us guessing, and we've no doubt Elliott might have had a thing or two to say about Jess' recent over-sharing!
Jess, meanwhile, is enjoying Marbs as a single lady for the first time in three years and she hasn't ruled out a holiday romance.
Eyeing up her co-star and former flame Dan Edgar, Jess told her pal Ferne McCann: "Me kissing Dan? Who knows?!"
"It's Marbella," she said. "A lot of stuff goes down in Marbella... He's really sweet, he's gorgeous."
She was also spotted getting quite friendly with TOWIE newcomer Peter Wicks over a game of beach volleyball too.
Watch this space, perhaps?!
