So One Direction are straight back to work now they've jetted on over to America, but before they settle in for those long ol' 7 hours on 1D Day, they stopped by the X Factor USA studios to visit their Uncle Simon and give a little performance.
And while us lot here in the UK are still waiting for the weekend when we can see the boys having a special sing song with the likes of Olly Murs and JLS, this is probably a nice way to warm things up, right?
Yep, the boys looked pretty smart as they appeared on the X Factor USA stage and gave another swoonful performance of their latest single Story of My Life - and trust us, there was swooning involved.
