Jesse Williams, who plays Dr. Jackson Avery on 'Grey's Anatomy,' knows how to keep a secret. He and wife Aryn Drake-Lee are expecting their first child -- in just two months.

Williams met Drake-Lee, a real estate broker, back when he was a New York school teacher (he's been on 'Grey's' since 2009). The pair dated for about five years before tying the knot in September of 2012.

A source close to the couple told Us Weekly the infant is due in December, and that Drake-Lee had a baby shower in Brooklyn late last month.

Our best wishes to the expectant parents.
