"Imposter" is a song by English singerâÂÂsongwriter Louis Tomlinson from his album How Did I Get Here? It was released on 20 January 2026 as the album's third and final single before its release on 23 January.
The song was written by Nico Rebscher, Dave Gibson, and Tomlinson, and was produced by Rebscher. The song talks about Tomlinson's struggles with Imposter syndrome and with self-worth. Of the single, Tomlinson states, "Imposter was written in the jungle in Costa Rica. Conceptually it leans into the idea of identity." He also states that the song is "probably the most melodic moment on the record".
Alex Harris for Neon Music says that "Imposter syndrome makes for neat interview copy. Every artist claims it now. But most donâÂÂt build the syndrome into the song's architecture. Tomlinson did." Harris also claims that the song "insists it belongs on playlists next to confident indie hitmakers whilst the lyrics undermine that claim." Eva Elisa Wells of OffTheRecordPress praised "Imposter" as it "blends its lyrical vulnerability with moody production", and that the "shift in confidence" contributes to a "bolder and brighter album."
