"Break the Ice" is a song recorded by American singer Britney Spears for her fifth studio album, Blackout (2007). It was released as the third and final single from Blackout on March 3, 2008, by Jive Records. The song was written by Nate "Danja" Hills, Jim Beanz, Keri Hilson and Marcella Araica, while production was handled by Danja and vocal production was handled by Beanz. "Radar" was originally planned to be released as the third single, but "Break the Ice" was released after it was chosen by a poll on Spears's official website. Musically, "Break the Ice" is an electro-R&B song with influences of crunk. The song opens with a choir and features synthesizers. Its lyrics deal with an attraction between two people. "Break the Ice" received generally favorable reviews from music critics, who deemed it a strong electronic song from the record.
"Break the Ice" was a moderate success, reaching the top-ten in Belgium, Canada, Finland and Sweden, and charting within the top 40 in Australia, New Zealand and many other European countries. In the United States, the single reached number 43 on the Billboard Hot 100, while peaking at number one on the Dance Club Songs chart. An accompanying music video, directed by Robert Hales, was released on March 12, 2008. The anime-influenced animation video was based on the superheroine character of Spears's "Toxic" video, and portrays her destroying a highly secured laboratory with several clones, including one of herself. A remix of "Break the Ice" was used as a video interlude during The Circus Starring Britney Spears (2009) and was performed for the first time during her residency show at Planet Hollywood Las Vegas, Britney: Piece of Me (2013–17).
