We can all agree that July 23 is a very important day and will most likely go down in history. Why? Well, it’s actually the day that One Direction was created! That’s right. The British boy band, made up of Harry Styles, Niall Horan, Liam Payne, Louis Tomlinson and Zayn Malik, was formed by Simon Cowell on The X Factor — and the monumental moment took place on July 23, 2010. Wow, that means it’s officially been nine years since our favorite group was formed, and we seriously cannot believe how fast time has flown by!

Liam and Louis both took to Twitter to celebrate the special anniversary, and their messages made us pretty emotional, TBH.

Nine years… Amazing to look back at all the memories and even now you got us trending worldwide after nine years. You truly are the best fans in the world #9YearsOfOneDirection,” the “Strip That Down” crooner wrote, while his former bandmate added, “So many incredible memories. Days like today are days for reflection, so proud looking back! Thank you for ALWAYS having our backs! Big love to the lads! #9YearsOfOneDirection.”

OK, is anyone else crying? We know we are. Well guys, you might want to grab some more tissues because in honor of the big day, we decided to round up some then-and-now pictures of the guys to appreciate how much they’ve grown up over the years! You’re seriously not going to believe how much they’ve all changed since the band started. One thing’s for sure — they’ve all certainly come a long way.

Scroll through our gallery and see photos of the One Direction guys when the band first started and join us in appreciating their major glo’ ups!
