The minute we met,
I could feel it inside
The love I was tryin' to hide
It must have been my heart
That gave me away
I was so sure I was playin' it cool
You made me feel like a fool
It must have been my heart
That gave me away
Now I'm just hopin' my heart
Won't do it again
'Cause I know by the look in your eyes
You're walkin' away, this is the end
The minute you came
Walking in through the door
It just didn't feel like before
It must have been your heart
That gave you away
You and me been together so long
You know you
Never were good at puttin' me on
You didn't have to tell me
That something was wrong
It was your heart that gave you away
It must have been your heart
That gave you away
It must have been your heart
That gave you away
Now I'm just hopin' my heart
Won't do it again
'Cause I know by the look in your eyes
You're walkin' away, this is the end
You and me been together so long
You know you
Never were good at puttin' me on
You didn't have to tell me
That something was wrong
It was your heart that gave you away
It must have been your heart
That gave you away
It must have been your heart
That gave you away
It must have been your heart
(It must have been your heart)
That gave you away
(That gave you away)
It must have been your heart
(It must have been your heart)
That gave you away
It must have been your heart
(It must have been your heart)
That gave you away
It must have been your heart
That gave you away
It must have been your heart
That gave you away
It must have been your heart...
