The baby would arrive in December, said a source close to the "Grey's Anatomy" actor, who plays Jackson Avery in the long running medical drama series, reports aceshowbiz.com.
Williams, 32, and Drake-Lee, 33, first met when Williams was still working as a school teacher in New York. They dated for more than five years before they got married.
The couple exchanged vows in September 2012.
