And the baby boom on the Grey’s Anatomy set continues! It all began back in 2009 when star Chyler Leigh welcomed daughter Anniston in May. Since then, four more babies have been added by Ellen Pompeo, Katherine Heigl (during her Grey’s stint), Eric Dane and Jessica Capshaw. Now Sarah Drew is adding to the baby boom! A rep for the actress confirmed that she and husband Peter Lanfer are expecting their first in January. No word yet on whether they’ll be welcoming a son or a daughter.
