"Say You'll Be Mine" is a song by British dance-pop group Steps, released as a double A-side with a cover version of Kylie Minogue's "Better the Devil You Know". Steps' cover of "Better the Devil You Know" was later included as the opening track on their third studio album, Buzz (2000), but did not serve as a lead single. A limited-edition single was released as a digipack that was included with a doubled-sided poster in the sleeve. The song is the first to feature all five members on lead vocals.
