Pregnant Snooki Has a Baby Bump “Naked Appearance” on Family Vacation (PHOTOS)

Even on vacation, Snooki is sticking to her fit pregnancy. Now that's dedication!

The former Jersey Shore star took to Instagram over the weekend, posting a video of herself working out in the gym during a family vaca. In the video, Snooks is working out her arms on a machine when the handlebar accidentally lifts up her shirt and reveals her baby bump! "Babygirl accidentally wanted to make a naked appearance ... No breaks on vaca! #fitpregnancy, she wrote, alongside the video.

Bare belly and all, Snooki is looking fantastic. She is six months along and expecting a daughter with her fiancé Jionni LaValle. But before the baby comes, Snooks, her hubby-to-be, and their son Lorenzo, are getting into summer mode with a little vacation. The Jersey mama has been posting photos from the trip, and, in the words of Deena Nicole, it looks like a good time!
