Mom-to-be Keri Russell is back to work.
Photos showed Russell smoking while in character as undercover spy Elizabeth Jennings. (Don’t worry, a rep for the series tells PEOPLE that the cigarette is fake.)
In the scene, a pregnant Russell appears to be in a phone booth, puffing on the cigarette in a large brown coat that hides her baby bump.
A source confirmed to PEOPLE earlier this month that the Felicity alum is expecting a baby with Rhys, 41.
The 39-year-old actress is already mom to daughter Willa Lou, 3, and son River, 7. This will be Russell’s first child with Rhys.
A friend of the couple previously told PEOPLE that Rhys and Russell are “thrilled” about their new little one.
