 "Oh no, not my baby; oh no, not my sweet baby
 Oh no, not my baby; oh no, not my sweet baby
 Not my girl"

 When my friends told me you had someone new
 I didn't believe a single word was true
 I told them all I had faith in you
 I just kept on sayin':

 "Oh no, not my baby; oh no, not my sweet baby
 She don't go with other guys
 & I don't think she would tell me lies"
 My mama told me when rumors spread
 There's truth somewhere & I should use my head
 But I didn't listen to a word she said
 I kept right on sayin':

 "Oh no, not my baby; oh no, not my sweet baby
 She's not like these other girls, you see
 & I believe she's in love with me
 Oh no no no no no, not my girl"

 Well, you might have had a last-minute fling
 But I am sure it didn't mean a thing
 'Cause yesterday you accepted my ring
 & now I'm glad that I just kept on sayin':

 "Oh no, not my baby; oh no, not my sweet baby
 Oh no, not my baby; oh no, not my sweet baby
 Not my girl, not my girl
