"Two Hearts", alternatively titled "2 Hearts", is a song first recorded by British electronic duo Kish Mauve, written for their 2005 self-titled extended play and later re-recorded by Australian singer Kylie Minogue for her tenth studio album, X (2007). Both versions were written and produced by Jim Eliot and Mima Stilwell. Minogue's version was released on 9 November 2007 by Parlophone as the album's lead single. The song was Minogue's first commercial single since "Giving You Up" (2005), as she was diagnosed with breast cancer in May 2005. After the announcement, Minogue took a hiatus between of two years to recover from her illness.
