Fans of NBC's The Voice now know everyone who will be helping the superstar coaches when the show returns for its fourth season in March.

It was announced today through Access Hollywood that Lady Antebellum's Hillary Scott will be the mentor for Team Adam. She and Adam Levine previously collaborated on the song "Out of Goodbyes," which appeared on Maroon 5's third studio album, Hands All Over.

Access Hollywood is a production of NBC's parent company, NBCUniversal.

This follows the previous reveals of the other three mentors. Team Blake has enlisted the services of Sheryl Crow, while Team Usher will have Pharrell Williams, and Team Shakira is joined by Good Charlotte's Joel Madden - who is himself a coach on the Australian version of The Voice.

The Voice returns on March 25.
