Rihanna, U2 and Justin Bieber are to feature on a new album being rushed out to help the people of Japan.

Universal Music are putting the digital only album together to raise funds and it could be out by the end of this week.

A spokesman said, "We are doing it only digitally because it is faster, and this will be a worldwide release. The plan is to have it available later this week,".

Lady Gaga is part of the Universal Music team but we've yet to hear if she is taking part.
