U2, Jay-Z and producer Swizz Beatz have teamed up to raise money for survivors of the earthquake in Haiti.
Speaking to RTÉ 2fm's Dave Fanning, U2 guitarist The Edge said the stars wrote, finished and recorded a song last week.
He said: "Bono got a call from a producer, Swizz. He and Jay-Z wanted to do something for Haiti.
"So Bono came up with the phrase on the phone and last night we were here, we wrote a song, finished, recorded, and sent it back to them.
"So, that might be the next thing you hear from us."
The BBC reports that on his Twitter page, Swizz Beatz said: "Me, Bono, Hova [Jay-Z's nickname] have something to say about Haiti. Stay tuned."
The Edge, Bono, Jay-Z and Rihanna are scheduled to appear as part of the Hope for Haiti telethon on Friday, which will be aired on MTV.
