Ginnifer Goodwin & Josh Dallas Bring "Baby" to Once Upon a Time Season 4 Set—See Photos of Them & 3 Others!

The two, who welcomed their first child in May, were joined by Jennifer Morrison (Emma), Colin O'Donoghue (Hook) and Georgia Haig (Elsa)

Did you know Snow White and Prince Charming were a couple of pranksters?

Ginnifer Goodwin and Josh Dallas recently returned to the Once Upon a Time set in Vancouver more than a month after the birth of their first child. With extra security in tow, the married pair arrived on Wednesday, July 16, and the 32-year-old actor was seen carrying a baby carrier. Inside was a doll.

"Everyone was constantly smiling, so happy and relaxed, even played and joked around with the fake baby!" a witness told E! News.

The doll appeared to have been part of the storyline, as Show and Charming welcomed a child in the previous third season of the ABC fairy tale series. Goodwin, 36, gave birth to her and Dallas' son, Oliver, on May 29. Their real child was not seen on set.

His parents appeared very affectionate there, and not just to each other—the actor pretended to give another man a lap dance, the witness said.

"It appears Josh has been working out," the witness added. "He looks good."

Other cast members spotted on the set of ABC's fairy-tale series included Jennifer Morrison, who plays their adult daughter Emma Swan, and Colin O'Donoghue, who portrays her dashing love interest, Captain Hook (aka Killian Jones).

Season 4 of Once Upon a Time began filming earlier this month and is set to premiere on Sept. 28. Viewers will get to see the return of recurring character Robin Hood, played by Sean Maguire, as well as new ones from Disney's 2013 film Frozen.

Scott Michael Foster, who played Cappie on ABC Family's Greek, will portray Kristoff, Elizabeth Lail has been cast as Anna and her sister Elsa will be played by Australian actress Georgina Haig (see the first photo of her in costume). Haig was spotted on the set as well, with O'Donoghue, wearing civilian clothing but sporting Elsa's side-braid hairstyle and carrying an umbrella.
