Last night, Jack, Lisa and little Pearl headed to the Bellagio hotel on the Vegas Strip to watch a performance of Cirque du Soleil's show 'O'.
Following the performance, Jack shared a cute snap of the trio posing outside the theatre entrance.
Commenting on Instagram, he said: "Just finished @cirque #O with pearl & @mrslisao. Make sure to check it out if you're in Vegas, it's incredible."
The Osbournes started their holiday in style last week, boarding a private jet to take them off skiing in colder climes.
While on the slopes, the family were joined by Jack's sister and Pearl's aunty, Fashion Police host Kelly Osbourne.
Posting a snap of herself and her sister-in-law Kelly on her own Instagram account, Lisa joked: "Sn0w bunNe3z @kellyosbourne."
Jack, Lisa and Pearl have since jetted to Vegas to continue their fun-filled winter break and, while there, have also been hitting the many casinos.
Well, Jack and Lisa have at least!
In one photo, the couple look like they've come straight out of a 40s gangster flick. Lisa also told her followers: "Putting on our poker faces & getting ready to win #Vegas."
