A single to raise money for those affected by the Grenfell Tower fire has topped this week's chart - despite only being released on Wednesday morning.
More than 50 stars including Stormzy, Rita Ora and Liam Payne recorded Bridge Over Troubled Water to support victims' families and survivors.
The track sold 170,000 copies in less than 48 hours - the vast majority of which were download sales.
The cover of the Simon and Garfunkel classic was organised by Simon Cowell.
Dua Lipa - who appears on the track - told the BBC: "It's such a special song. I feel really honoured and grateful to have been a part of it.
"To see so many artists come together for such a great cause, and to see the community come together, it's really sad and upsetting but to know that together we can help the families that have lost loved ones, it's very important."
The song had the biggest first day sales of any single released this decade, shifting 120,000 copies, according to the Official Charts Company.

Over on the album chart, Royal Blood went straight in at number one with their second album How Did We Get So Dark?
The group told the BBC: "To have a career and make another record that has taken us to this kind of level is not only something we didn't expect, but something we didn't even contemplate... it's incredibly exciting."
Nickelback's ninth studio album Feed The Machine entered at number three - marking the band's first top 10 album in 10 years.
