It was Sia's turn to help James Corden get to work last night, as she popped her wig and bow on for a seriously epic carpool karaoke.
But aside from proving she's got the best voice in the business, she also demonstrated exacty why she really should've kept all those songs she wrote for other people.
As the comments under the vid point out, Sia 'could've really done good for herself' with a track like that. Sorry Rihanna, but it really does sound great when she sings it.
Also, HOW FREAKY ARE HER EGG-HOLDING HANDS.
