Kardashian West confirmed she and West are expecting their fourth child via surrogate back in January on an episode of 'Watch What Happens Live with Andy Cohen' after the host asked if she was "working on another child." "We are," Kardashian West responded. The news of the new baby comes a year after Kim and Kanye welcomed daughter Chicago via surrogacy.
