Ooh, I bet you're wond'rin' how I knew
Baby, baby, baby, 'bout your plans to make me blue [how]
With some other girl you knew before
Between the two of us girls ya know I love you more
It took me by surprise I must say
When I found out yesterday.
Don't ya know that I heard it through the grapevine
Not much longer would you be mine
Oh, don't ya know that I heard it through the grapevine
