AceShowbiz - A new additional member may be coming to Hawkins, Indiana. Fans of "Stranger Things" are going crazy after a new set photo from upcoming season 3 seemingly suggests that one character of the Netflix series is having a bun in the oven.

In the recently-leaked set photo, Joyce (Winona Ryder) was seen donning a loose-fitting white T-shirt underneath an oversized navy shirt. While her outfit didn't give significant details of what to come in the new season, fans notice that she had an an unusual bigger bump in the midsection. It prompted fans to speculate that Joyce might be pregnant.

Should she be, it may spark another question among fans. Did the alleged baby was Bob's child? Did he manage to get Joyce pregnant before he was painfully torn apart by Demodogs?

Another theory might be it's Hopper's baby. At the end of season 2, Joyce and Hopper got cozy that it should be a surprise if the unborn child is Hopper's baby.

So far, there's no word about the matter. Fans of the critically-acclaimed sci-fi series will have to wait for season 3 to learn whether Joyce is really pregnant and who's the baby daddy.

While it's unclear whether another little Byers is coming, the show will be welcoming a slew of new castmembers for season 3. Recently added to the cast was "Haters Back Off" alum Francesca Reale, who was tapped to play Heather. Heather is described as a popular lifeguard at the Hawkins community Pool. She will become the center piece of a dark mystery, though the exact details about how she will factor into the story is kept under wraps.

Reale will join Cary Elwes and Jake Busey, who are cast as Mayor Kline and Bruce respectively. Mayor Kline is described as a "handsome, slick and sleazy quintessential classic '80s politician," while Bruce is a "journalist for The Hawkins Post with questionable morals and a sick sense of humor."

Millie Bobby Brown reprises her role as Eleven, joining fellow returning castmembers Finn Wolfhard, Gaten Matarazzo, Caleb McLaughlin and Noah Schnapp. Also among returning actors are Cara Buono, Dacre Montgomery, Sadie Sink, David Harbour, Natalia Dyer and Joe Keery.

"Stranger Things" is expected to return for season 3 in 2019 on Netflix.
