"Everytime" is a song by American recording artist Britney Spears, taken from her fourth studio album, In the Zone (2003). It was released on May 10, 2004 by Jive Records as the third single from the album. After her relationship with American singer Justin Timberlake ended in 2002, she made friends with her backing vocalist Annet Artani. They started writing songs together at Spears's house in Los Angeles, and then traveled to Lombardy, Italy, where "Everytime" was written. Spears composed the music and she developed the lyrics with Artani. According to Artani, the song was written as a response to Timberlake's 2002 song "Cry Me a River". Spears has neither confirmed nor denied these allegations.
