The song Oh No Not My Baby is performed by Cher .
When my friends told me you had someone new
I didn't believe a single word was true
I showed them all I had faith in you
I just kept on saying
Oh no, not my baby
Oh no, not my sweet baby
You're not like those other guys
Who lead you on and tell you lies
My mama told me when rumors spread
There's truth somewhere and I should use my head
But I didn't listen to a word she said
I kept right on saying
Oh no, not my baby
Oh no, not my sweet baby
You're not like those other boys
Who play with hearts like they were toys
Well, you might have had a last minute fling
But I am sure it didn't mean a thing
'Cause yesterday you gave me your ring
And now I'm glad that I kept on saying
Oh no, not my baby
Oh no, not my sweet baby
You're not like those other guys
Who lead you on and tell you lies
Oh no, not my baby
Oh no, not my sweet baby
Oh no, not my baby
No, no, no, no, not my sweet baby
Oh no, not my baby
Oh no, not my sweet baby
Oh no, not my baby
No, no, no
