O to the M to the F to the G! One Direction shared the title of their next single from 'Midnight Memories,' out Nov. 25, by posting individual baby photos on Twitter. Too cute.

The song, titled 'Story of My Life,' is said to drop later this month -- Oct. 28 is the day. Mark those calendars, Directioners.

Pop acts are using Twitter and images in a creative fashion when delivering key information about their new albums. At midnight, Lady Gaga tweeted out the song titles from 'ARTPOP' via photos of the individual track names as part of a mural created by her little monsters.

Now, 1D mined their personal scrapbooks for baby photos, which are so adorbs we can't stand it, to share the good news.

Directioners and PopCrushers, which 1D member was the cutest as a little tyke? We can't decide, so argue amongst yourselves after "oohing" and "aahing" at these precious pics.

They were adorable THEN and they are adorable NOW! We're loving those bowl cuts on Harry Styles and Louis Tomlinson, by the way.
