5SOS have officially #MadeIt and Niall Horan couldn't be prouder

Niall can't stop fanboying over their latest success.

By Sammy Stewart

By now you're probably well aware that Niall Horan loves another band ~sLighTy~ more than his...

Over the weekend 5 Seconds of Summer achieved a MAJOR career milestone when they performed at New York's Madison Square Garden.

Aside from the entire 5SOS fam getting hella emosh about their boys' success, somewhere in the world Niall Horan was crying tears of joy.

First off he commented on Ashton's post, "delighted for you and the boys Ash, it really is amazing. You'll always be able to say you played at Madison Square Garden."

Next up, Niall made sure to wish his ol pal Luke Hemmings a happy birthday with THE hottest #TBT of all time...

Oh, and then Niall remembered it was his adorable little nephew Theo's birthday. Rather than post just any photo in honour of his little lad, Niall made sure to pick a picture that also had ~5SOS vibez~.

We sure as heck hope that Niall + 5SOS golf date happens soon...
