Niall Horan Rocks Out With Undies On His Head! Watch HERE!

And here we didn’t think Niall Horan could get any more adorbzies!
The totes silly One Direction goofball is still a little boy at heart, and he clearly has no plans to grow up.
Niall let it all hang loose – including his underwear (kinky!) – during a recent night in.
And thanks to Harry Styles and the magic of Twitter, we all got a glimpse!
Not only did Niall sport some saggy socks on his hands for a dance party, but he also had some fresh undies on his head.
And by the looks of those underoos, we suspect they were his!
Ch-ch-check it out (above)!
But what we really want to know is WHO is that blonde there with them??
