Happy birthday today to our favorite blondie from the boy band One Direction (R.I.P.): Niall Horan! Horan turns 23 today and the former 1D star has a lot to celebrate after the past year.

Though the post-1D era has been difficult for the group’s loyal fanbase, things are certainly looking up for its talented former members and Horan's future is surely bright. Not only does the young (and, um, way good-looking) singer have the vocal chops to carry him far, but he's also got the comic timing of a veteran stand-up. Plus, after all that the One Direction guys have been through together over the years, something tells us that they'll have each other's backs long after the 1D era comes to a close.

And so, here's to Horan on his birthday! In the spirit of celebrating his big 2-3, we decided to take a trip down memory lane by rounding up our favorite moments between the birthday boy and his former 1D bandmates. Grab your tissues because it's pretty dang adorable.

And, just one final pic for good measure:
