"Fuck You" is a song by English singer Lily Allen from her second album, It's Not Me, It's You (2009), as her third international single. A maximalist pop track, its lyrics dismiss and ridicule a bigoted antagonist, criticising their racism, homophobia, and war-mongering. The song was a hit in mainland Europe, topping the chart in Flanders for three weeks and reaching number two in Wallonia and the Netherlands. It became a top-five hit in Finland, Norway, and Switzerland, reached the top 20 in several other European nations, and peaked at number 23 in Australia.
