Calling all Disney's "Frozen" fans - Kristoff is also coming to "Once Upon A Time" and he will be living with Anna in the castle too. Actor Scott Michael Foster himself shares the latest scoop on "OUAT'" Kristoff and his romance with Anna in Season 4.

"Frozen" in "Once Upon A Time" season 4 will pick up exactly where it left off with Anna and Kristoff's relationship stronger than ever. In the fairytale-inspired show, Foster tells Hollywoodlife.com that Kristoff and Anna are obviously together.

"He's obviously with Anna. At the end of the movie, they're together," said Foster. But they're not just together, they are actually living together in Arendelle Castle.

How is royalty treating Kristoff? The actor shared details about how his character transformed into a man of royalty from his humble beginnings as a rugged mountain man.

"He's a rugged mountain man who grew up with trolls, so there's a bunch of avenues he can take to expand his character, based off him not being used to palace life," Foster explained.

He also said that "Anna is the apple of his eye." So for those who are thinking that Kristoff might fall in love with the gorgeous Elsa (they have scenes together), think again.

Everyone is excited to see the "Frozen" sisters in "OUAT" and especially the character who will play the villain. There are rumors that it will be the Ice Queen.

Meanwhile, fans of the show and Disney's "Frozen" can enjoy seeing the cartoon characters come to life. We could just hope that Sven and Olaf comes to life too.

"Once Upon A Time" season 4 returns to the small screen on September 28.
