THROWBACK: Today’s #throwback is Britney’s 2003 song “Breathe on Me.” While never released as a single off her fourth studio album, “In the Zone,” Britney performed the song prior to the album’s release, and it was always a fan-favorite. At the time of its release, the song was often described as Britney’s — “most sensual song” — off the album. During her Vegas residency, “Piece of Me,” Britney would later add this song to the line up when the show was revamped. #britneyspears #throwback #inthezone #breatheonme #pieceofme #lasvegas
