The loved-up couple posed for a photo at the fun fancy dress bash, which appeared to be held for Georgia Kousoulou's birthday.
Jess looked gorgeous in a white crop top teamed with a pink midi-length tulle skirt. She accessorised with a chunky pink statement necklace from online boutique Sally Jacks, and finished off her look with a sparkly gold hairband.
Ricky looked like Jess' Prince Charming, wearing a dapper suit and keeping in theme with a pink tie. The reality star posted the cute snap to Instagram with a love heart symbol - ahh!
Sharing the same photo, Jess said: "Filming today in my @renekcouture skirt love it! #barbie&ken."
The couple looked sun-kissed following their recent trip to Marbella, where they managed to stay out of the ongoing drama with their co-stars, which viewers have witnessed in the recent Only Way Is Marbs specials.
In fact, it appears Jess and Ricky became "agony aunts" to their co-stars during their stay in the Spanish city. "We helped everyone out and gave everybody advice when we could," Jess recently said.
This week, Jess gave fans a sneak peek of her new clothing range as she got to work designing new items for her Lipstick Boutique collection.
