Shakira

Tuesday's season finale of The Voice was not only an emotional night for Cassadee Pope, who was named the Season 3 winner, but also for the show's coaches. When the singing competition returns in March, it will be without original coaches Christina Aguilera and CeeLo Green, who are both sitting out Season 4 to focus on other projects. Anyone worried about their absence, or how the additions of Usher and Shakira will affect the show's chemistry, can officially relax, according to social media correspondent Christina Milian.

"It's going to be powerful. It's going to be fun. We're all nervous because it's a new start," Milian told TVGuide.com backstage after Tuesday's season finale. "But I think they have a lot to offer. They're very competitive already, so now they're going to have a little fun. You have people like Blake [Shelton], who's going to make it easy, and the same thing with Adam [Levine]. They're in it already, so any advice Usher and Shakira need, they can go to them."

After having seen the new group in action during the pre-taped blind auditions for Season 4, Milian already sees a new rivalry starting to form between the coaches. "Maybe Shakira against all the boys," Milian said. "She's really intelligent and she's great at campaigning for someone to pick her." Better than "used car salesman" Adam?! We can't wait to see that.
