LOS ANGELES (AP) - Shakira and Usher held their own as new coaches on "The Voice," although Usher needs a geography lesson. He referred to Nashville as a state. Blake Shelton would not let him live that down. Usher is on his way to building his team, though, with two singers. Team Blake picked up a guy who sang "Sexy and I Know It" on acoustic guitar, blonde identical twins and a 16-year-old whose first big performance was her audition for "The Voice." Team Shakira won over a musician who works as a roofer and a guy who surprised the judges because they thought only a woman could hit notes that high. Adam Levine has only one singer for his team, but she's got experience. She was supposed to be Michael Jackson's duet partner for his final shows and sang at his memorial service.
