We didn't think it was possible to love them any more than we already did.

One Direction were on The X Factor results show last night performing their new single Gotta Be You and it was AMAZING! We weren't really expecting anything but awesomeness from the boys but they just seem to get fitter every second!

Louis Tomlinson didn't seem to know what to do with himself during the slow number, probably because he has far too much energy, so he just started sort of smacking his bum. Nice.

It was intense, especially when Harry Styles hit those high notes. They pierced right through our very hearts.
