Harry Styles, Niall Horan, Liam Payne, Louis Tomlinson and Zayn Malik each took to Twitter to tease the upcoming single.
But rather than just write a quick promo tweet, they gave the fans a little somethin'-somethin': the most adorable pics of themselves as kids!
Yep, fetus 1D boys, FTW.
We've rounded up their tweets and pics so you can gawk at it all in one location.
Also, while we know nothing about "Story of My Life" (ballad or upbeat?), we can only imagine that including these throwback pics and many more of the guys would make a pretty fantastic music video.
Louis Tomlinson announced the single, writing: "So our next single is gonna be Story of My Life !"
The official One Direction Twitter account shared the good news of a release date, after the boys shared their cutie kid pics, writing: "YES - the guys' next single 'Story of My Life' will be available to download 28th October! 1DHQ x #StoryOfMyLifeSingle2"
Niall added, "I think story of my life is my favourite song on midnight memories! Can't wait for it"
"Story of My Life" is the second single from One Direction's upcoming Midnight Memories album.
