Ginnifer addressed her pregnancy during season 3 of "Once Upon A Time," and dished with fans about coming back to work on set after giving birth to her baby.

"I think you know that I spent my hiatus being pregnant followed by a surprise ending in which I had baby, so we are having a lot of fun being back at work full-time," Ginnifer said, HollywoodLife.com reports. At one point, she motions down to baby Oliver in the stroller.

Ginnifer also jokes about "postpartum emotions," and after a stunt guy tells her that there are no more cheesy puffs at the craft table, she smacks him across the head with a weapon.
