Bob Geldof has launched a new Band Aid initiative to help raise money for the fight against E bola.
The new stunt, which works in a similar way to the ALS Ice Bucket challenge, saw the Boomtown Rats star sing Bono's line from the charity's song Do They Know It's Christmas? before nominating three others to do the same, reported the Daily Mirror.
And to kick things off, Bob performed the line: "Tonight, we're reaching out and touching you," and then challenged Damian Lewis, Dominic West and Richard E Grant - who he described as "the creme de la creme of British acting" - to follow suit.
The trio have 24 hours to complete the challenge, otherwise they have to donate £100 to Band Aid.
If they do it, they have to nominate three more to do the same and donate £10 to the charity.
"I'm doing this to help raise awareness this Christmas about the fight against the Ebola virus," Bob said.
"I've got a bunch of celebs lined up who are going to do it. Find out more about the cause and make a donation, as I have, at bandaid30.com/donate or text AID to 70707 to give £10 (UK Only)."
Band Aid's co-writer Midge Ure also took part, before challenging Moby, Heaven 17's Glenn Gregory and Paul Strasburger.
One Direction, Ed Sheeran, Ellie Goulding, Olly Murs and Emeli Sande feature on the new version of Do They Know It's Christmas?, which hit the top spot when it was released in November.
The new recording - which became the fastest selling single of the year - marks the 30th anniversary of the song, which was originally put together to raise funds for famine relief in Ethiopia.
