Tomorrow is a very important day Directioners. It's Niall Horan's 21st birthday! Although he'll be spending part of his birthday on stage since One Direction has a show that night, we have a feeling that Niall won't be that upset about it. After all, what's better then knowing that a sold-out stadium sized crowd is spending your birthday with you?
In honor of the singer's special day, we decided to round up some flashback photos from Niall's childhood. Prepare yourself for the cuteness overload you're about to experience!
Click through the gallery and let us know in the comments which pic is your fave! Don't be too surprised if you end up having a giant smile on your face after looking through them all. Niall was just a super adorable kid!
