Check out Liam Payne sharing an adorable message for the birthday boy, who Liam leads you to believe is quite a 1D fanboy. It's a good thing it's a quickie video, because we might just drown in feels if he carried on much longer.
Liam says: "Hi Niall Horan, it's Liam of One Direction. I've heard you're a very big fan, I've also heard it's your birthday so I wanted to wish you a happy 21st birthday. Hope you have a good one. See you soon."
Liam's bodyguard shared the special video message on Instagram, writing: "Happy birthday @niallhoran I hear you are huge fan, so I got you a little gift. Happy 21st mate."
Best. Gift. Ever.
