In one pic, Jen showed off her chic holiday style, posting a snap her black off-the-shoulder dress by Finders Keepers, which she pared with a pair of white Adidas sneakers and a pop of red with her Louis Vuitton bag.
She topped off the look with a camel coloured hat to protect her face from the harsh Roman sun.
"Chill'n at The Trevi fountain ... It had to be done! #rome," she write alongside another pic of herself, this time tucking into some delicious looking gelato.
As well as tucking into some gelato, the couple have been taking in some culture, with Jen posting a video from The Vatican, "Wow 🙊 #Italy #rome," she captioned the video.
