Mariah, Jewel, Sinead, Boyz II Men To Honor Nobel Winner

November 17 [7:55 EDT] -- On Monday, Mariah Carey is expected to announce that she will be joining Jewel, Sinead O'Connor, and Boyz II Men in Oslo, Norway next month to honor this year's Nobel Peace Prize winner.

Anti-landmine activist Jody Williams will be honored at the December 11 concert, and some of the proceeds from the show will go to the international campaign to ban landmines. Previous Nobel concerts had always featured classical music until last year, when Joan Osborne and African singer Angelique Kidjo performed.
