"Halo" is a song recorded by American R&B singer Beyoncé Knowles for her third studio album, I Am... Sasha Fierce (2008). Included on the I Am... disc, it was intended to give a behind-the-scenes glimpse of Knowles' life, stripped of her make-up and celebrity trappings. Columbia Records released the song, the album's fourth single, to mainstream radio in the United States on January 20, 2009, and to international markets from February 20. Inspired by Ray LaMontagne's 2004 song "Shelter", "Halo" was composed by Ryan Tedder, Evan Bogart and Knowles. It was conceived by Tedder and Bogart specifically for Knowles, although there was media speculation that it had been intended for Leona Lewis.
