Well this should make for an interesting Season 4! As resident judges Christina Aguilera and Cee Lo Green prepare to take time off from "The Voice" to focus on other projects, new coaches Shakira and Usher will be joining the remaining original panel members, Blake Shelton and Adam Levine. The only problem is, Blake and Shakira are having some serious difficulties communicating on set due to their thick accents.

According to Adam, the cast is simultaneously filming Seasons 3 and 4. And if that isn't confusing enough, the Maroon 5 frontman revealed that exchanges between Oklahoma-born Blake and Colombia-native Shakira are getting lost in translation. "The only thing is Shakira and Blake have a hard time because they don't understand each other's language!" Adam revealed on "The Ellen DeGeneres Show."

"And even though Blake is speaking English, surprisingly enough, he just kind of says, 'What are you talking about? What are you even saying? I don't know,'" Levine continued. "So they just don't understand the accents that they have. It's funny."

"The Voice" Season 4 premieres March 25, 2013 on NBC.
