In between all the girlfriend showing off in New York, and the trips to Taylor Swift's hotel room with washbag in hand, One Direction have actually done a bit of that singing thing that they're quite good at whilst in the Land of Dreams.
The boys did a beautiful performance of Little Things on one of America’s most popular programmes, The Letterman Show.
After a nice chat on the biggest couch in the universe, 1D plonked their delicious little arses on the most envied speaker boxes in the world to do their acoustic performance.
Also incase you didn't know, Niall got snogged by Dustin Hoffman, which was, err... weird. But he didn't seem to complain too much.
For the performance, there was a lot of moody stares, smouldering eyes and heart melting harmonies. You just never let us down do you guys? SWOON.

Are you a mess of hormones and unrequited love on the floor right now too? Cool, glad we’re not the only ones.
