The 27-year-old blonde bombshell was dressed casually for her errand run, which also saw her visit a pharmacy.
Jessika donned a pair skintight denim jeans and a simple white T-shirt, pairing the minimalist look with a pair of black slip ons.
True to her trademark style, the former office administrator sported a full face of makeup and wore her platinum tresses in boho waves.
Jess kept her hair off her face with a pair of wayfarer sunglasses.
The outing comes after Jessika sent fans into meltdown with a since deleted Snapchat photo which seemed to prove she is expecting her first child!
The reality star shared a photo of herself on the social media platform which showed her posing in a tight blue dress with an obvious bump.
Jessika quickly deleted the image, but not before eagle eyed fans screenshotted it for evidence.
A close source to Jessika told Daily Mail Australia: "I think she meant to send it to someone privately but accidentally added it to her [Snapchat] Story, which all of her contacts could see.
"Jess deleted it with a few seconds, as if she just realised she'd made a huge error."
