The Voice Season 6 had a lot of changes from the get-go with the departure of Cee Lo and Christina Aguilera, replacement judges Shakira and Usher are now back from Season 4.

While Usher was fantastic in the fourth season with his unconventional coaching techniques and gimmicks, the Hollywood reporter notes that at the season premiere, Shakira seems to be the star. With a flare of sass in the air, Shakira and Usher are the two judges that people will be keeping an eye out for throughout the competition.

Although it's too early to tell, Shakira and Usher definitely bring the fire in the show's two-hour premiere Monday night. As the returning judges join Black Shelton and Adam Levine on the red chairs, Shakira is a ball of spice as she fires with some one-liners at her fellow judges, says the Hollywood Reporter in another article.

"Adam's too busy thinking about his wedding, all he thinks about is flower arrangements," says Shakira to one singer and promises to be laser focused this season.

Usher knows not to mess with Shakira, saying: "You don't want to see that woman mad. I actually am very cautious when analyzing her. She's very protective, as any woman would be, but man, she is just passionate about what she's doing and you don't want to cross the line. It's better just to stay out of it," says Usher to host Carson Daly and Executive Producer Mark Burnett.

Another highlight of the premier was the performance of Dawn and Hawkes who veteran judge Levine labeled his "favorite in 'Voice' history." After a pitching battle with Latina beauty, Shakira, the duo went with Adam who was obviously happy.
