They’re gearing up to fill in for Christina Aguilera and Cee Lo Green on “The Voice,” and Shakira and Usher are featured in a new spread of promo pics.

The “Hips Don’t Lie” songstress and her “U Remind Me” cohort look like naturals in the infamous swivel chairs they’ll occupy once Season Four gets started on March 25th.

And in a recent interview, a pregnant Shakira expressed her (and her baby boy’s) excitement over the gig. “I’m thrilled to be here and I’m sure he is too.”

Of the transition, Blake Shelton shared, "The dynamic has changed for sure. It's really fun." Usher added, “I’ve been able to bring out his inner MC Hammer.”
