"The Voice" coach Christina Aguilera chose Green Day frontman Billie Joe Armstrong to be her team's mentor.
A tweet from the show's staff said: "Welcome Billie Joe (@BJAofficial) to #TeamXtina! We are ready to rock out in Season 3."
Armstrong is joining three new mentors on the show: Rob Thomas (who's with Cee Lo Green); Mary J. Blige (Adam Levine); and Michael Buble (Blake Shelton).
The third season of "The Voice" premieres September 10th.
