The 12th season -- which will see Carson Daly returning as host -- is set to begin in February.
Miley Cyrus will return as coach for the 13th season, which is to kick off in the fall of 2017. The rest of the Season 13 coaches' lineup will be announced at a later date.
"We can't wait to experience the unique chemistry and energy Gwen, Alicia, Blake and Adam will bring to Season 12," Paul Telegdy, president of the alternative and reality group at NBC Entertainment, said in a statement Tuesday. "With Miley returning for Season 13, we're truly ecstatic about the unmatched musical know-how and talent coming together in our coming seasons."
Season 11 is airing now with Levine, Shelton, Keys and Cyrus as mentors, and Daly as host.
