In honor of their new spin-off series and Nicole ''Snooki'' Polizzi's impending motherhood, EW recently toted the mom-to-be and BFF Jenni ''JWoww'' Farley to Babies ''R'' Us in Secaucus, N.J., for a little shopping, and a lot of talk about where babies come from. Once inside the kiddie emporium, JWoww spent a good part of the afternoon riding around on this bicycle. Snooki demurely refrained from cycling: ''I can't get on a bike — my vagina will pop out.''
