The reality is that the snap is from Jess' old modelling days.
The 27-year-old originally shared it to Instagram.
Donning a wedding dress by Meeting Grace, she wrote, "Had the best day wearing these amazing gowns by @meetinggrace."
Still modelling, Jess left little to the imagination during a recent lingerie shoot.
"Who else starts to miss the weekend this time of the week?!" she penned.
"I hope you all have a magical weekend - I'll be spending mine enjoying the beautiful weather and having a few cocktails with my girlfriends living my best life."
