Jess' cousin Leah Wright shared some photos of the 'Dance All Night' singer with her arm wrapped around a man's neck, in what appears to be a club.
Another snap, although a little blurry, shows the pair giggling on the dancefloor.
Commenting on the photos, Leah said "Oh dear", followed by, "Love it @MissJessWright_".
No doubt Jess was letting her hair down as she wrapped up her final night on the Spanish island. There's nothing better than dancing the night away!
Jess has been lapping up the sunshine with her co-stars - Gemma Collins, Billie Faiers, Ferne McCann, Lydia Bright, Danielle Armstrong, Chloe Sims, Lauren Pope, Bobby Norris, Vas J Morgan - for the past few days.
But after Leah shared the photos last night, a fan commented: "Oi oi lol good on you girl x."
Newly-single Jess ended her two-and-half-year relationship with Ricky last year, and it didn't initially end on the best of terms.
The couple called it quits on an episode of TOWIE in November after Jessica accused Ricky of sending flirtatious messages to another girl on Twitter, although he insisted nothing further happened.
The pair engaged in a war of words on Twitter, but they patched things up in December, and were filmed saying a final goodbye during scenes shown on The Only Way Is Essexmas.
