It's been five years since the birth of One Direction, and what a five years it's been. Directioners across the world are reflecting on the boy's journey so far by using the hashtag #5YearsOfOneDirection.

It's not just the fans that are getting involved with this, the boys themselves have taken to Twitter to show their appreciation for everyone that has helped them along the way and it's SO adorable.

Fans are especially losing it over one member of 1D's thank you tweets, that being Louis Tomlinson's. The 23-year-old has been weirdly quiet since the news that he'sbecoming a dadwas confirmed,so fans were over the moon when he finallybrokehis silence, even if the tweets did not address the baby.

Harry Styles has also shown his appreciation for the Directioners on his Twitter page. The pop star began a series of emotional tweets by saying: "it is impossible to thank anyone enough for all the support they have given us over this time.." Aww, Harry! We're welling up!

WE LOVE YOU ONE DIRECTION! Here's to another five years!
