"2 Become 1" is a song by the British girl group the Spice Girls. Written by the group members, together with Matt Rowe and Richard Stannard during the group's first professional songwriting session, it was produced by Rowe and Stannard for the group's debut album, Spice (1996). "2 Become 1" is an R&B-influenced pop ballad that features instrumentation from a guitar, an electronic keyboard and string instruments. The lyrics focus on the bonding of two lovers, and also address the importance of contraception. Its Big TV!-directed music video, which features the group performing against time-lapse footage of Times Square in New York City, was completely shot against a blue screen at a studio in London. The backdrop was later superimposed.

The Spice Girls are an English girl group formed in 1994, consisting of Mel B ; Melanie C ; Emma Bunton ; Geri Halliwell ; and Victoria Beckham. With their "girl power" mantra, they redefined the girl-group concept by targeting a young female fanbase. They led the teen pop resurgence of the 1990s, were a major part of the Cool Britannia era, and became pop culture icons of the decade.
