You and I go hard
At each other like we going to war
You and I go rough
We keep throwing things and slamming the doors
You and I get so
Damn dysfunctional we stuck keeping score
You and I get sick
Yeah I know that we can't do this no more

[Hook]
But baby there you again, there you again making me love you
Yeah I stopped using my head, using my head let it all go
Got you stuck on my body, on my body like a tattoo
And now I'm feeling stupid, feeling stupid crawling back to you
So I cross my heart, and I hope to die
That I'll only stay with you one more night
And I know I've said it a million times
But I'll only stay with you one more night

Try to tell you no
But my body keeps on telling you yes
Try to tell you stop
But your lipstick got me so out of breath
I be waking up
In the morning probably hating myself
And I be waking up
Feeling sastified but guilty as hell

[Hook]

Yeah baby give me one more night
Yeah baby give me one more night
Yeah baby give me one more night

[Hook]

(Yeah baby give me one more night)

So I cross my heart and I hope to die
That I'll only stay with you one more night
And I know I've said it a million times
But I'll only stay with you one more night
