"All the Things She Said" is a song recorded by Russian music duo t.A.T.u. for their second, and first English-language, studio album 200 km/h in the Wrong Lane (2002), and released as the lead single from the album in Europe on 9 September 2002 by Universal. It was written by Sergio Galoyan, Trevor Horn, Martin Kierszenbaum, Valery Polienko and Elena Kiper, while production was by Horn. "All the Things She Said" is a translated and reworked version of their 2000 song "Ya Soshla s Uma", included on their debut album 200 Po Vstrechnoy (2001). It was later included on their compilation albums t.A.T.u. Remixes (2003) and The Best (2006). Although its original story was based on a dream Kiper had at a dentist appointment, manager Ivan Shapovalov evoked the theme of lesbianism in both this and the English-language version. The lyrics describe two girls developing feelings for each other.

t.A.T.u. are a Russian pop duo consisting of Lena Katina and Julia Volkova. The two started out as part of the children's musical group Neposedy before being managed by producer and director Ivan Shapovalov and signing with Russian record label Neformat. t.A.T.u.'s debut album 200 Po Vstrechnoy (2001) was a commercial success in Eastern Europe, and that resulted in the duo signing with Interscope Records to release its English-language counterpart, 200 km/h in the Wrong Lane (2002). The album was certified platinum by the IFPI for one million copies sold in Europe and became the first album by a foreign group to reach number one in Japan. It was also certified gold in the United States and included the international hits "All the Things She Said" and "Not Gonna Get Us". The duo represented Russia in the Eurovision Song Contest 2003 with the song "Ne ver', ne boysia", finishing third.
