OUAT fans, meet your new favorite TV couple! Once Upon a Time has cast Scott Michael Foster and Elizabeth Lail in new Frozen roles, TVLine confirmed on Tuesday, July 1.

The Greek alum has landed a recurring role to play Kristoff in the fairy tale series. Newcomer Lail will play Anna, his love interest and Queen Elsa of Arendelle's younger sister. It's yet to be confirmed which actress will be taking on the lead of Elsa.

It was first revealed that Frozen would be coming to the ABC show during its season 3 finale in May. During the final scene, a blue liquid magically turned into Elsa, never revealing her face. "Get ready…" the official handle for the show tweeted afterward, along with a still photo from the scene. "#Frozen is coming to #OnceUponATime."

Frozen debuted in November 2013 and is currently the highest- grossing animated movie in history. Jonathan Groff and Kristen Bell were the original voices of Kristoff and Anna in the film, which also starred Idina Menzel (Elsa) and Josh Gad (Olaf).
