It's been a long night, you've had a few too many tequilas and when you and your friends jump in the back of your Uber all you want is for the driver to turn up Magic FM and you all to have a singalong.
That's the case too, it seems, for Ellie Goulding and Lorde.
The pair filmed themselves in the back of a car this weekend singing their hearts out to Britney's Hit Me Baby One More Time.
We can't exactly verify what happened pre- this video being filmed but what we do know is a) we're big Ellie and Lorde fans, and b) we are even bigger Britney fans, and c) combining the three has made for a musical masterpiece.
We're obviously now keeping everything crossed for Ellie and Lorde to team up for a 90s pop cover album.
