"She Said" is the second single from British musician Plan B's second album The Defamation of Strickland Banks — a concept album whose songs tell the fictitious tale of a sharp-suited British soul singer who finds fame with bitter-sweet love songs, but then loses everything when he ends up in prison for a crime he didn't commit. The single was released as a digital download and on CD single on 24 February 2010. "She Said" was the sixteenth best selling British single of 2010.
"She Said" began to receive increasing amounts of radio airplay throughout February and March 2010. BBC Radio 1 in particular was supportive of the track up until its release. Plan B performed the single on the 12 March 2010 edition of Friday Night with Jonathan Ross. He also performed on Conan on 19 April 2011. The song was also featured in the start of the pilot episode of Whitney.
The music video for "She Said" was directed by Daniel Wolfe and shows the soul singer Strickland Banks, played by Plan B, in court following the events of the "Stay Too Long" video. The video also stars actress Vicky McClure as Strickland Banks' girlfriend and Kaya Scodelario as the female lead.
