Singers Usher and Shakira are all set to judge the new season of singing reality show "The Voice".
The superstars have replaced Christina Aguilera and Cee Lo Green, who left the show to concentrate on their own music endeavors, said the Hollywood Reporter. On the season's premiere episode, the coaches performed the opening number and each of them played an instrument.
Shakira played the harmonica, Usher and Blake Shelton took on the guitar, and Adam Levine pounded the drums.
The competition between coaches is also said to be tougher than ever before as Levine said regarding Shakira, "You have a pregnant, hormonal Colombian... She's ready to bust some heads. She ain't messing around."
The fourth season of "The Voice" premiered yesterday.
