Hot N' Cold

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'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
You, should't really want to go, oh
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
