“Frozen” has officially taken over Storybrooke on “Once Upon a Time.” Season 4 newcomer Georgina Haig took to Twitter early the morning of July 14 to post a first-look photo of ABC’s version of Princess Elsa, who “Frozen” fans might know better as Disney’s Snow Queen.

“Ah yes but you see this isn’t me but my distant cousin Princess Someonelsa,” the Australian actress joked on the social media site. “#OUAT #Frozen #OnceUponATime.”

The photo, which is a “KASI Photos exclusive,” is blurry. Still, fans of Haig’s were able to quickly figure out that the blonde beauty in the photo wasn’t the “Once Upon a Time” actress. Despite the long braid and sparkly blue costume, the woman in the picture is more than likely a double instead of the real Snow Queen, played by Haig. The Aussie star noted as much in her reference to “Princess Someonelsa.”

Haig was added to the cast as Elsa in early July, a couple of days after Elizabeth Lail and Scott Michael Foster signed on as Anna and Kristoff. While it’s unclear if “Once Upon a Time” will pick up before or after Elsa and Anna’s joyous reunion in “Frozen,” viewers already know that a new villain is on the horizon.

A synopsis for Season 4 of the hit ABC series was released online late last week to pump up fans for the fall drama:

“Master storytellers Edward Kitsis and Adam Horowitz (“Lost,” “Tron: Legacy”) invite everyone to join Emma Swan, Snow White, Prince Charming, The Evil queen, Hook and all the other resident fairy tale characters as they prepare to defend themselves against a magical force from the past that’s too dark and unpredictable even for Rumplestiltskin -- The Ice Queen.”

The actress playing “The Ice Queen” hasn’t been confirmed, but fans are speculating that she'll be played by new addition and “Lost” alum Elizabeth Mitchell. According to Entertainment Weekly, Mitchell’s mysterious role will be part of the “Frozen” story arc on “Once Upon a Time” and will take place after the events that occurred in the 2013 Disney animated movie.

“Once Upon a Time” will return to ABC in the fall. Check out the tweet from Elsa’s Georgina Haig below and tweet your thoughts to @AmandaTVScoop.
