We can't believe it's been two years since One Direction burst onto the music scene.
The five piece boyband - who were put together during the X Factor UK boot camp stage back in July 2010 - have thanked fans on their second birthday.
Harry Styles, Niall Horan, Liam Payne, Louis Tomlinson and Zayn Malik celebrated their two-year anniversary as a collective by thanking their fans for all of their support since X Factor.
"Guys its been 2 years today since we were formed, its been incredible so far, its all down to you guys! Love you all soo much ! Thank you," Irish Niall Horan tweeted.
Zayn Malik added: "Wow 2years, what an amazing journey and its all down to you guys. Thank you, sending my love to you all #2yearsof1d"
The past two years have seen One Direction finish third on The X Factor in 2010, have an international number one single ('What Makes You Beautiful') and album (Up All Night) and embark on a world tour. They have achieved enormous success Stateside, including embarking on a sell out Up All Night tour.
