The Green Day musician will partner Christina Aguilera in NBC's upcoming third season of the talent show.
"Welcome Billie Joe (@BJAofficial) to #TeamXtina!," the series' official Twitter feed read. "We are ready to rock out in Season 3."
Armstrong revealed that he and his family are big fans of the show, and is looking forward to taking part.
"[The Voice is] not moulding artists, it's just giving them a little bit of guidance and direction without giving them a complete makeover," he told The AP.
The singer recorded his first appearance on the show on Wednesday (July 25).
He will join the previously announced season three mentors Rob Thomas (Cee Lo Green's team), Mary J Blige (Adam Levine's team) and Michael Buble (Blake Shelton's team).
Green Day will release their new album ¡Uno! on September 25, followed by ¡Dos! on November 13 and ¡Tré! on January 15, 2013.
