If you’ve never seen the BBC Radio 1 Heart Rate Monitor Challenge, it’s basically your standard talk show interview — but with a heart rate monitor constantly updating you on how excited or upset the celeb is!
In this case, Nick Grimshaw grills Maisie Williams about her celeb crushes, her boyfriend Ollie Jackson, and of course embarrassing naked and drunk stories.
But it’s special guest Eddie Redmayne who really puts the screws to the Stark sis.
He offers up three possible endings to Game Of Thrones just to see how she reacts!
Ch-ch-check out the vid (above) to see if Maisie’s heart gives anything away!
