"Kids" is a duet by Robbie Williams and Kylie Minogue, released as the second single from Sing When You're Winning, Williams' fourth studio album and the third single from Light Years, Minogue's seventh studio album. Williams and then songwriting partner Guy Chambers co-wrote the song for Minogue. Williams liked the song enough to turn it into a duet. The track was written when Minogue approached Williams to write her some songs for what would be her first album under Parlophone, Light Years, it was then, when Williams felt the chemistry and decided to include the track on his album and release it as a single, it was an instant hit when it was released in October of that year.
The song became a smash hit in the United Kingdom, reaching number-two and selling over 200,000 copies being certified Silver by the BPI. The track also broke into the top ten in several other countries including New Zealand, Mexico and Argentina as well as hitting the top twenty in Australia, being certified Gold in the latter for sales over the 35,000 copies. The lyrics, although penned by Robbie Williams and Guy Chambers, makes numerous references to the careers of both Minogue and Williams. Minogue's lyric "I've been dropping beats since Back in Black" is a self-deprecating reference to her 1980s pop image when she was known as the singing budgie from Australia—Back in Black being a 1980s album by Australian band AC/DC and of a stark contrast to her own style at the time. Later, in 2010, this song is used as the theme song of Junior Masterchef Australia.
