The Lead Radius Experiment (PREX) has provided the first model-independent evidence in favor of a neutron-rich skin in Pb. Although the error bars are large, the reported large central value of 0.33,fm is particularly intriguing. To test whether such a thick neutron-skin in Pb is already incompatible with laboratory experiments or astrophysical observations, we employ relativistic models with neutron-skin thickness in Pb ranging from 0.16 to 0.33 fm to compute ground state properties of finite nuclei, their collective monopole and dipole response, and mass-{\sl vs}-radius relations for neutron stars. No compelling reason was found to rule out models with large neutron skins in Pb from the set of observables considered in this work.
