Once I heard it for the first time through my headphones - I heard what it was she was actually saying. So I googled for the lyrics and confirmed she was saying something entirely different. I've been going around singing this song in my head for a while now - singing the wrong lyrics - I still like my version better.
can't read my, can't read my
no, he can't read my poker face
What I thought she was singing:
Cutie pie, Cutie pie
no, can't read my poker face
