"Riddle" is a song recorded by American R&B group En Vogue. It was written by Denzil Foster and Thomas McElroy, along with band members Cindy Herron, Maxine Jones, and Terry Ellis, for their fourth studio album Masterpiece Theater (2000), while production was helmed by Foster & McElroy. An angry mid-tempo song about a sneaking, cheating lover, "Riddle" is built around a clapping game motif, and interpolates the band's 1992 song "My Lovin' (You're Never Gonna Get It)." Lyrically, it has the protagonist revealing her feelings about discovering that her love interest is having an affair with someone else over the course of the week.
