‘The Voice’ is lining up yet another big name for its ninth season with the announcement that Rihanna is to be the new key adviser.

This comes hot on the heels of the news that Gwen Stefani would be one of the four judges when the singing competition returns on September 21st on NBC. The network’s president Robert Greenblatt announced on Thursday (August 13th) at the TCA press conference in Beverly Hills that the ‘B**** Better Have My Money’ singer would be playing a major role.
