The pregnant Jersey Shore star recently took part in the grand opening of the Earl of Sandwich at the Showboat Atlantic City Hotel & Casino, where she cut the ribbon and unveiled "Gorilla Beach," her own monstrous sandwich consisting of grilled chicken strips, mozzarella cheese, seasoned bread crumbs, Roma tomatoes, Italian dressing and, of course, pickles.
Joined by fiancé Jionni LaValle, the reality starlet seemed to be "in a great mood," an onlooker tells PEOPLE. "She was taking pictures with some of her fans."
Adds the source, "There was a really cute moment where Jionni was holding her tummy while she was also holding her tummy when she was signing copies of her book, Gorilla Beach."
