There are a lot of wet T-shirts and some actual bare torsos in the video, giving us here at Team Reveal confusing feelings about these barely legal lads.
It's another unquestionably catchy pop tune and, with lyrics like "I know we only met, but let's pretend it's love", one that's designed to drive impressionable girls absolutely mental.
Really, videos like this should come with a health warning: "If you have a heart condition (or you are female and aged 16 or under) beware: Harry Styles takes his shirt off."
'Live While We're Young' is the first single from the boys' second album Take Me Home and was leaked on the internet yesterday forcing the boys to release it early.
The boys performed in London last night as part of the iTunes festival, belting out old favourites like 'What Makes You Beautiful' alongside covers including Kings of Leon's 'Use Somebody'.
The hit-makers took a break mid-show to answer some Twitter questions, like "What are the defining characteristics of each member?" leading Zayn to call Harry "sexy". No word yet on how many girls fainted but it's safe to assume a few.
