We've come to love Britney Spears' dancing videos on her Instagram, and she gave us another one late Monday night -- dancing to none other than one of our new faves, Billie Eillish! It appears that Brit was feeling like going hard in what appears to be her dining or living room to Billie's hit "Bad Guy". Billie, who is a big Britney fan, caught win of this pretty quickly, leaving a simple comment on Brit's Instagram: "OMG"
We're sure Billie was freaking out! Check out the video below.
