It looks like McSteamy is back on diaper duty!
Rebecca Gayheart and Eric Dane welcomed their second child on December 28, a daughter named Georgia Geraldine.
The new arrival joins big sister Billie Beatrice, who turns two in March.
A rep for the 40-year-old actress told PEOPLE that “Both mom and baby girl are happy and healthy. Billie is thrilled to be a big sister and dad is getting ready to live in a house full of ladies!”
Dane, 39, plays Dr. Mark “McSteamy” Sloan on the hit ABC show “Grey’s Anatomy.”
