Winter is coming to "Carpool Karaoke," as the Apple Music version of the series just released a sneak peek at its upcoming "Game of Thrones" video.

The footage shows stars Maisie Williams and Sophie Turner rocking out to Justin Bieber's "Sorry" and Miley Cyrus' "Wrecking Ball" before deciding to treat the series' fans to a big surprise.

"They're the most loyal fans in the world and I think we should surprise them," Turner says, before the two are seen hiding amongst the dead bodies inside an escape room HBO set up during SXSW earlier this year.

The series also dropped a promo for its segment with Ariana Grande and Seth MacFarlane.

Their episode appears to be a Broadway-themed one, as the two sing "Suddenly Seymour" from "Little Shop of Horrors" and "What Is This Feeling?" from "Wicked" before attempting to show off their french horn skills.

Warning: they don't have any.
