“Lovebird” is a song recorded by British singer-songwriter Leona Lewis for her third studio album Glassheart (2012). It was written by Bonnie McKee, Joshua Coleman and Dr. Luke, and produced by Josh Abrahams, Ammo and Oligee. “Lovebird” was recorded at Pulse Recording in Los Angeles and is a power ballad, incorporating a piano and synth-driven melody. The lyrics consist of Lewis informing her past lover that enough time has passed since their relationship for her to have moved on and to have developed as a person. Critics praised Lewis’ vocal performance, likening the her technical abilities to those of Mariah Carey and Whitney Houston. The musical structure of the song was heavily compared to one of her previous singles, “Bleeding Love”, along with songs performed by Adele. The accompanying music video shows Lewis trying to escape from a giant bird cage.
To promote “Lovebird”, Lewis performed the song on talk shows Daybreak and Loose Women in the United Kingdom, in addition to singing competition La Voz in Spain. Nonetheless, “Lovebird” sold fewer than 600 copies upon its release, failing to attain one of the top 200 chart positions on the UK Singles Chart; however, two weeks after the release of Glassheart, “Lovebird” peaked at number 22 on the South Korea Gaon Single Chart due to strong digital download sales.
