The reality TV star, designer and author, 30, channeled her inner ice princess when she dressed to impress for the ITVBe's festive finale, filmed this weekend (Saturday 28 November).
And while we don't yet know the current situation between Jess and sexy Pete Wicks, we have a feeling his jaw might have hit the ground when he saw her!
Less of the ice princess, more of a hot babe!
Wearing stunning face jewels and body shimmer, Jess' sheer chiffon-style dress completed the dreamy look.
Sharing a couple of stunning photos on her official Instagram account, Jess told her one million followers: "Today's Ice Princess look dress from @houseofcb."
Don't worry, we checked for you - the gorgeous dress, a peach lace and mesh maxi, costs £169!
She also thanked her make-up artist, adding: "Ice Princess vibes today for filming once again @krystal_iammakeup has excelled herself."
Jess' co-stars Danielle Armstrong and Chloe Sims also embraced the ice princess theme and NAILED it.
Danielle - our I'm A Celebrity blogger! - wore a fabulous backless outfit, the 'Grace' lace dress with pearl detail from Rene K Couture. And, yes, it IS from their bridal range!
Meanwhile, Chloe also chose a frock from House Of CB. She opted for the Satordi rose gold sequinned floor-length dress, a striking party choice at £199.
She tweeted her fans: "Feeling Christmassy after yesterday's filming... Esp loved this dress."
The hour-long Christmas episode was partly filmed in Woodhall Manor in Suffolk, while some was filmed in Scotland earlier this month.
This weekend, it was reported that Lauren Goodger, Mario Falcone and Gemma Collins are all returning to TOWIE for the Chrimbo special.
The Only Way Is Essexmas is due to air in December.
