Tomorrow! You and me got a whole lot of history #10YearsOf1D

What a journey… I had no idea what we were in for when I sent this text to my Dad ten years ago at this exact time the band was formed. Thanks to everyone that’s supported us over the years and thanks to the boys for sharing this with me #10YearsOfOneDirection

Feeling pretty emotional today. 10 years!! Spent the morning watching old interviews and performances. Just wanted to send a massive thank you to ALL of my band mates. What we did together was incredible

Too many incredible memories to mention but not a day goes by that I don't think about how amazing it was. Niall Horan Harry Styles. Liam zayn . So proud of you all individually.

And to the fans. The people who gave us all these amazing opportunities. You are incredible, your unmatched level of loyality is something that makes me really really proud.

Miss it every day!

Louis Tomlinson Harry Styles. Liam zayn Love you ❤️
