It's the Stark sister road trip of your dreams.

Game of Thrones' Maisie Williams and Sophie Turner feature in the latest episode of Carpool Karaoke, filmed back in March in Texas during South by Southwest.

A sneak peek at the full episode sees the duo revive an old game where they'd read sentences in their very best Sean Bean (AKA Ned Stark) impersonations, or like they were Jon Snow on top of the Wall, "staring out at all the wildlings".

And so the young Starks threw out a couple of classic phrases including "Hakuna Matata: what a wonderful phrase!", "It's-a me, Mario!", and the entire spoken word intro to Mix-a-Lot's "Baby Got Back".

Unfortunately, Sean Bean wasn't there to judge the results himself, but it's pretty fair to say their efforts were impressive; though they did have to work out the right way to say "butt".

The full episode also features covers of Britney Spears' version of "My Prerogative" and Justin Bieber's "Sorry". They join a stellar line-up of previous guests including Will Smith, John Legend, and Alicia Keys. Also newly released is an episode combining the talents of Seth MacFarlane and Ariana Grande.
