Niall shared his thoughts on Instagram, writing, "When I met these four gents there was no way I thought we would go on to do what we did. So many unbelievable memories we shared together. We felt the adoration of millions from around the planet on a daily basis and it was mind blowing. It's such a major part of our lives and always will be. Cheers to US today boys and thank you to all you beautiful people who have supported us over the last 10 years. @liampayne @harrystyles @zayn @louist91 ❤️ #10yearsofonedirection."
