"My Affair" is a song by British singer and songwriter Kirsty MacColl, released by Virgin on 29 July 1991 as the second single from her third studio album, Electric Landlady.

"[7] On its release as a single, Tom Doyle of Select wrote, "Kitschy Latin cabaret offering with a quirky lyric about parents who tell you to cut your hair and having steamy afternoon clinches.

"[8] Steve Lamacq of New Musical Express described it as "one of the swinging moments" from Electric Landlady and a track which "suggest[s] that she'[s] taken to listening to Andy Kershaw a lot".

He added, "Still, not her best, and rather off-the-point, with Kirsty sounding like a cross between Sandie Shaw and Lady Penelope, while the song mingles with images of right-on restaurants and Adrian Mole.

[10] In a review of Electric Landlady, Adam Sweeting of The Guardian wrote, "The surprise success of the bunch is 'My Affair', where an army of Hispanic musicians under the direction of Angel Hernandez go salsa-crazy behind La MacColl's cool vocals.

"[11] Barbara Jaeger of The Record said of the song, "A Latin jazz feel permeates the tune, and MacColl handles the supple phrasing with elegance if not ease.

"[12] Stewart Mason of AllMusic described the song as a "brilliant track" and a "sublime single", adding that it was "MacColl's first full-fledged foray into Latin music".
