"Once Upon A Time" season 4 cast Ginnifer Goodwin's baby boy makes his Comic-Con debut as the actess gets busy filming the series in Canada.

In a video posted on YouTube, "Once Upon A Time" season 4 cast Ginnifer Goodwin's baby Oliver makes a cameo as she addressed the Comic-Con attendees.

The video starts, "Hi Comic-Con! Greetings from Vancouver! Thank you tech guys. I really wish I could be down there with you today but I was needed here on set. I think you know I spent my hiatus being pregnant, followed by a surprise ending in which I had a baby, so we are having a lot of fun being back at work full time."

"Once Upon A Time" season 4 cast Ginnifer Goodwin was unusually giddy when addressing the crowd as the video sets up the joke, "Some people said I might find myself in a sort of post-partum emotional state but I'm great!"

"Between you and me, I think that post-partum's a myth," she adds.

Then a crew comes in and comments, "Kraft has just run out of bloody cheesy puffs."

At that point, she takes the blunt weapon from a knight and slammed it on the crew. All thoughout, "Once Upon A Time" season 4 cast Ginnifer Goodwin's baby boy was presumably sleeping on the stroller.

According to HollywoodLife, Ginnifer Goodwin is currently in Vancouver to film scenes for the fourth season of the OUAT,which will follow the "Frozen" story arc.

Attending the Comic-Con panel on Saturday were Georgina Haig (Queen Elsa) as well as showrunners Edward Kitsis and Adam Horowitz, Deadline added. The producers also showed a clip of the "Once Upon A Time" season 4 premiere episode, which revealed the return of Giancarlo Esposito as the Magic Mirror.

Also shown in the clip are Queen Elsa and Princess Anna (Elizabeth Lail) laying flowers on their parents' grave.
