One Direction, Ed Sheeran + More Sing 'Do They Know It's Christmas'

One Direction joined Ed Sheeran, Ellie Goulding, Bono, Chris Martin, Sam Smith, Rita Ora and countless other A-List artists as Band Aid 30, giving the world a star-studded rendition of 'Do They Know It's Christmas'.

The video was first unveiled last night (Nov. 16) on the 'X Factor,' and proceeds of the purchase of the track (which you can buy on iTunes) will go to help stop the spread of Ebola.

While the track is jam-packed with superstar celebs, each A-lister gets their moment to shine, with 1D kicking off the Christmas song, followed by turns from Ed Sheeran, Rita Ora and countless others. And while it's swoon-worthy to hear all of our favorite acts sing the holiday tune, most importantly, we're humbled by their dedication and desire to stop the deadly disease.

Watch One Direction, Ed Sheeran, Ellie Goulding and so many more celebs cover 'Do They Know It's Christmas' in the video above.
