Rita Ora, Ellie Goulding, Paloma Faith, One Direction and Emeli Sande have recorded a new version of the Band Aid charity single marking 30 years since the original.
You know, that infamous track which raised £8 million back in 1984, the one organised by the legendary Sir Bob Geldof? Well, this year he's calling it Band Aid 30.
The stars were spotted arriving at the Sarm studios in west London Saturday morning to round up the final recordings before the single airs for the first time on ITV's X Factor results show on Sunday at 8pm.
What's more is that Ellie Goulding, Sam Smith, Chris Martin and Bono have also recorded a version of 'Do They Know It's Christmas?'
Rita was looking pretty sharp in a red two-piece suit (all about the wide-leg trousers) which she paired with a white crop top and trainers. The 23-year-old singer posted a photo of herself leaving this morning with the caption:
"Band aid 30. Support the cause. Thank you sir bob! It's out tomorrow everybody do your part! Now off to the voice! #TeamRITA #chopper"
Ellie did Dennis the Menace stripes, black skinny jeans, patent biker boots and carried a black tote - perfect wares for an early Saturday morning start.
Then there was Paloma Faith who turned heads in a smart monochrome ensemble. Think embellished shirt, trousers, ankle boots and beautiful black wool trench coat belted at the waist. She meant business.
Other celebs doing their bit to back the cause raising money and awareness for those suffering with Ebola included Nick Grimshaw and Pixie Geldof who pitched up this morning fresh-faced, coffee in hand.
The song will be made available to download at 8am GMT on Monday, priced 99p. And there's also a CD version costing £4 which will be released three weeks later with a cover designed by artist Tracey Emin.
LOVE RITA'S URBAN-STREET STYLE? It's no wonder she's collaborated with adidas Originals on an achingly cool collection.
