Michael Jackson passed away three years ago on Monday and that thought didn't escape the mind of a One Direction fan, who tweeted the lads to ask if they would sing one of his songs in memory of his passing.
Luckily, One Direction noticed said tweet, and sung a Michael classic at their show in Atlanta, Georgia last night.
There was hardly any hesitation (apart from asking Dan the guitar man if he could play it) before they went into a lovely rendition of Man In The Mirror, which we're sure had everyone in the audience blubbing.
We certainly were.
See how sweet that was?
But as you may have heard Louis say, that isn't the first time they've sung the Michael Jackson classic, just look at this video taken when One Direction were at bootcamp on the X Factor..
THEY ARE ALL SO YOUNG.
What do you think of One Direction singing a Michael Jackson song? Do you think it should become a permanent feature on their tour?
