Jay-Z and Coldplay have teamed up to raise money for the victims and families of the Sandy Hook school massacre.
The Watch the Throne rapper and the British rockers hope to raise $10,000 (£6,000) by auctioning VIP tickets to their New Year concert at the Barclays Center in Brooklyn, New York.
The Yellow hitmakers and Beyoncé's husband will ring in 2013 with a performance at the Brooklyn stadium and 10 lucky fans have the chance to win a luxury suite.
"This will be the second time in two years that Coldplay has celebrated New Year with long-term friend and collaborator Jay-Z, the band having shared the bill with him at a Las Vegas concert in 2010," Coldplay said.
Fans keen to party with the superstars at the show can bid for the tickets on CharityBuzz.com. The auction closes at midnight on 28 December.
The winner will also be able to meet Jay-Z and Coldplay backstage after the show.
According to the New York Post, they want to donate funds to the relief in Newtown, Connecticut, where lone gunman Adam Lanza killed 20 children and seven adults, including his mother.
All proceeds will be donated to Newtown Youth and Family Services, a local non-profit mental health clinic which aims to create a vibrant community.
Jay-Z launched the Barclays Center in his native Brooklyn with eight sold-out concerts last September.
