What Is The Song Title? "You're Hot Then You're Cold, Up Then You're Down In Then You're Out"

Hi

I think you are probably looking for "Hot n Cold" by Katy Perry.  

Cause you're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down
You're wrong when it's right
It's black and it's white
We fight, we break up
We kiss, we make up
(you)You don't really want to stay, no
(but you)But you don't really want to go-o
You're hot then you're cold
You're yes then you're no
You're in and you're out
You're up and you're down

You can find the rest of the lyrics HERE.
