Today is a very special milestone for One Direction: the band is celebrating 5 years together as a group! The group has been gracing TWIST's magazine covers for all five years, and we're getting very emotionaly (in a good way!) about their bandiversary today.
A lot can change in five years, and boy has it ever. From traveling all over the world on multiple world tours, to hitting the red carpet together in stylish ensembles, and even to Zayn Malik leaving the band, the guys have been through a lot together, and we've been there right along with them.
