Is you is or is you ain't my baby
The way you're acting lately makes me doubt
Youse is still my baby, baby
Or has that flame in your heart done gone out
A fella is a creature that, that has always been strange
When you think you're sure of one 
He's gone and made a change
Is you is or is you ain't my baby
Maybe baby found somebody new
Or is my baby still my baby true
Is you is, is you is or is you ain't my baby
The way you're acting lately makes me doubt
Youse is still my baby, baby
Or has the flame in your heart done gone out
A fella is a creature that has always been strange
Just when you think you're sure of one 
He's gone and made a change
Is you is, is you ain't my baby
Maybe baby found somebody new
Or is my baby still my baby true
A fella is a creature that has always been strange
Just when you think you're sure of one, girls 
Gone and made a change
Is you is, is you ain't my baby
Maybe baby found somebody new
Or is my baby still my baby true
Or is my baby
Is my baby still my baby true
