''X'' is a 2007 album by Australian recording artist Kylie Minogue. It is her tenth studio album release, her first release since 2004's greatest hits compilation ''Ultimate Kylie'', and her first studio album since 2003's ''Body Language''. ''X'' was preceded by lead single "2 Hearts" and released worldwide in November 2007. The American release of ''X'' came in April 2008, preceded by the single "All I See".
Work on the album began following Minogue's gradual recovery from breast cancer and subsequent radiotherapy treatment. Her cancer, which was diagnosed in May 2005, resulted in the postponement of ''Showgirl: The Greatest Hits Tour'' tour midway through its run. Minogue resumed the tour in late 2006, in the midst of recording ''X'', and was completed later in the following year.
In addition to positive critical reception, ''X'' was nominated for a BRIT Award for "Best International Album" and debuted at #1 in Australia, and in the top five in the United Kingdom. No official statement has been given on the sales of ''X'' but according to the UK newspaper ''The Times'', as of December 2008, ''X'' had sold one million copies worldwide.
On 3 December 2008 it was announced that ''X'' had been nominated at the 51st Grammy Awards in the category of Best Electronic/Dance Album, making it Minogue's 5th ''Grammy Award'' nomination.
