I remember, I was Mr. Cool
And then that you were just a hot little fool
Then you put your heat in me
Now I'm not how I used to be

'Cause my heart's on fire
It's burning me up
(Burning me up, burning me up)
My heart's on fire
It's burning me up
(Burning me up, burning me up)


Just got a feeling, I could do it over
You got it goin', now you put it out
I thought I told you not to play with that
But you keep turnin' up my thermostat


Now my heart's on fire
It's burning me up
(Burning me up, burning me up)
My heart's on fire
Yeah, it's burning me, burning me
Burning me, yeah


Then you put your heat in me
Now I'm not how I used to be


My heart's on fire
My heart's on fire, yeah


My heart's on fire, my heart's on fire
(Burning me up, burning me up)
My heart's on fire, my heart's on fire
(Burning me up, burning me up)


My heart's on fire, my heart's on fire
(Burning me up, burning me up)
My heart's on fire, my heart's on fire
(Burning me up, burning me up)
