Oslo  - US actress Scarlett Johansson was Tuesday named as one of the hosts of the upcoming Nobel Peace Prize Concert, organizers said.

Among acts slated to perform at the December 11 concert were Diana Ross along with Canadian singer-songwriter Leslie Feist, US country musician Dierks Bentley, singer Julieta Venegas, Nigerian musician Seun Kuti and Norwegian singer-songwriter Marit Larsen.

The concert is held the day after the Nobel Peace Prize ceremony where the 2008 winner, former Finnish president Martti Ahtisaari was to be honoured.

Ahtisaari was cited for his mediation efforts in countries ranging from Northern Ireland to Kosovo, Indonesia as well as negotiating Namibian independence from South Africa.

The show was slated to be broadcast to some 100 countries. (dpa)
