"Uncle Riley is right next door to us... and if he knew that we were going to drink and drive and get cigarettes - we'd be in that much trouble," Jessika says in the video.
"Ah s--t! I'm the middle of the road."
Police have not commented on the video.
This is not the first time Jess has been in a Snapchat scandal.
A couple of weeks ago, the 27-year-old shared a photo of herself to Snapchat, which revealed the MAFs star posing in a snug blue dress with a obvious 'bump'.
Jessika quickly deleted the image, but her fans were quicker by screenshotting the evidence before it was gone.
A close source to Jessika reveals toDaily Mail Australiathat, "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."
