"Sadie" was covered by musician R. Kelly,^[5] on his debut solo studio album titled 12 Play, released in 1993. It is the tenth song on the album. It was recorded by Kelly as a tribute to his mother Joanne Kelly, who died earlier that year.

Rapper Tupac Shakur sampled Sadie on his hit song Dear Mama, which just like the Spinners' original and R. Kelly cover, is a tribute to his mother, Afeni Shakur.^[6] However, in the chorus of "Dear Mama", "Sadie" is replaced with "lady".
