A baby is coming out in the "Once Upon a Time" season 5, and that's besides Zelena's.

This was inadvertently confirmed by actress Ginnifer Goodwin when she guested at "Jimmy Kimmel Live" to promote "Zootopia," a Disney film where she leads the voice of police rabbit Judy Hopps.

In her interview with Jimmy Kimmel, Goodwin hinted that the pregnancy of the actress behind the role of Belle, Emilie de Ravin, will be used in the series. While pregnant with her second child with "Once Upon a Time" co-star Josh Dallas, the actress said her pregnancy will not be incorporated in the plot of the show because one of her "Once Upon a Time" co-stars got pregnant in real life and that's going to be the one integrated in the plot.

Goodwin did not directly identify that co-star of hers, but fans of the series believe that she was referring to de Ravin. In fact, even the executive producers of the series suggested that the real-life pregnancy of the actress might be the one written into the series instead of Goodwin's.

The revelation makes it appear that Belle and Rumple still love each other enough to make the most of their marriage and welcome the growing baby in Belle's belly despite their wobbly marriage in the previous season.

Aside from another character's pregnancy, Goodwin also teased that something gripping is in store for her role as Snow and Dallas' role as Prince Charming.

In a previous interview, Dallas revealed that his character will deal with his past as he meets his brother for the first time in the Underworld.

"Once Upon A Time" season 5 episode 12 premieres on March 6 on ABC.
