Turns out, the father is not Jon Hamm. People magazine, citing a source, said Monday that Nicole “Snooki” Polizzi is not only reportedly pregnant, but engaged to boyfriend Jionni LaValle. "I know he's the one so I know the ring's gonna come soon," the Jersey Shore star told the magazine on Jan. 12. "Well, not soon-soon. He knows it should be big, cuz if it's small I'm saying no. Like, 'Get another ring!' "
