Jess cradled her baby bump as they soaked up the sun right next to the sea.
She opted for a gorgeous strapless dress which she accessorised with orange pieces included a pair of strappy heels and a crossbody bag.
She went with plenty of jewellery to elevate the outfit including chunky, silver rings and bangles.
Jess also shared pictures of her relaxing by the sea with her blossoming baby bump.
“Someone wants to join the pool party,“ she captioned the picture.
She sunbathed in a gorgeous leaf-patterned bikini.
They also enjoyed the nightlife of Lake Garda with Jess sharing a picture of Rob lounging on a beach looking out at the bay.
The sports pundit looked relaxed in a white linen shirt with a pair of khaki pants. He added a pair of white runners to complete the look.
In February, Jess shared a handful of pictures cradling her growing bump as well as a black-and-white shot with her husband Rob, his hand over her stomach.
”We’ve been praying for you,” she captioned the sweet pictures.
