One Direction Takes Us Back Through All Their Best Moments in Emotional 10th Anniversary Video

It's been 10 years since One Direction lit up our worlds like nobody else, and the now-solo members of the group came together on Thursday (July 23) to share an emotional look back at 1D's best moments.

The nearly five-minute YouTube clip, titled "10 Years of One Direction,' kicks off all the way back on the set of the song that started it all, "What Makes You Beautiful."

The montage, soundtracked by some of 1D's biggest hits, then floats through photo shoots, massive world tours, the group in interviews and in the studio recording all five of their albums.

"Five albums in five years sounds hectic, and it is hectic," Niall Horan admits, before Harry Styles adds, "The fans have obviously always given us so much, we always felt it was important to give them new music."

1D also took to Twitter to announce that throughout the rest of the week, they'll be unveiling 4K ultra HD versions of some of their music videos, starting with "What Makes You Beautiful" today. "Live While We're Young" will follow on July 24, "Story of My Life" on July 25, "Steal My Girl" on July 26 and "History" on July 27. The week will wrap up with a live stream of their Where We Are Tour - Live From San Siro Stadium on July 28.
