"Make No Mistake, He's Mine" is a song written by Kim Carnes and recorded as a duet by Barbra Streisand and Carnes in 1984 and subsequently by Ronnie Milsap and Kenny Rogers under the title of "Make No Mistake, She's Mine". Both versions charted.

Carnes said that in the wake of Glee's version with a man and woman singing about a female lover, there were now "three different meanings of the song", regarding this malleability of the piece as "rewarding and gratifying".

The song was recorded by Streisand and Carnes, co-produced (with Bill Cuomo) by Carnes, It was released on Streisand's 1984 album Emotion and released as a single in December 1984, it hit #8 on the Adult Contemporary chart and #51 on the Billboard Hot 100 in early 1985.

In 2002, the track would re-appear on Streisand's compilation Duets. It also surfaced as a solo recording by Carnes, as a bonus track on a CD reissue of Carnes' album Barking at Airplanes and as a track on Carnes' "best of" album Gypsy Honeymoon.

1985 saw Carnes become the first artist to appear on the Billboard charts as part of a solo (Invitation To Dance), duet (Make No Mistake, He's Mine), and trio (What About Me) at the same time.

Billboard said Streisand was "wonderfully feisty" in this duet. Orange Coast Magazine said the song featured "brilliant vocal performances", and sounded as contemporary in 1993 as it did in 1984. New Straight Times thought the "lovely song" was a great companion piece to The Girl Is Mine, due to its theme of possessiveness between rivals.

"Make No Mistake, She's Mine" was recorded as a duet single by country pop artists Ronnie Milsap and Kenny Rogers in 1987.
