Los Angeles - One Direction's Harry Styles, Louis Tomlinson Niall Horan have paid tribute to fans on the band's sixth anniversary.
The three of them took to Twitter to celebrate six years since the group - which also features Liam Payne, 22 - was formed on the UK X Factor.
One Direction's official account shared a video of Louis, 24, in which he said: "I just wanted to film a little message to say thank you, because you guys are incredible.
"Your continued support is remarkable really. And every single one of you had a hand in changing our lives and I hope you're as proud as we are."

And Harry's mother, Anne Twist, appeared to rubbish claims that One Direction will not get back together after their current hiatus, with a tweet that hinted there is more to come.
She wrote: "@onedirection Huge well done on everything you have achieved so far! (sic)."
Zayn quit the band in March 2015 to become a solo artist and earlier this year the group went on an indefinite hiatus.
Liam has signed a solo deal with Capitol UK, while Harry - who is filming Christopher Nolan's Dunkirk - and Niall have reportedly signed deals with Columbia and One Direction's label Syco, respectively.
Louis is believed to be planning to focus on his record label and TV work during the break.
