The news comes just days ahead of her Voice debut on season 10, on which she will serve as a key advisor mentoring all four groups of contestants. For season 11, she will serve as a coach alongside returning stars Adam Levine, Blake Shelton and Pharrell Williams.
The trio are all also on the current season alongside original coach Christina Aguilera. In recent years, Aguilera has taken off every other season off, with another female coach subbing in for her. First, it was Shakira, then it was Stefani. The latter is famously dating Shelton after the two met on The Voice. Stefani is currently in the midst of a busy promotional tour for her new album.
While other singing competition shows, namely American Idol, has known to stay with the same judges for several seasons in a row, The Voice has been known to mix up the talent sitting in those big red chairs so as to change the on-air dynamic. Other previous coaches include Cee Lo Green and Usher.

Cyrus, who famously became a household name on TV thanks to Disney Channel's Hannah Montana, released her fifth studio album in August. In addition to The Voice, Cyrus is also set to star in Woody Allen's Amazon TV series.
Although rising in age, The Voice continues to be an important part of NBC's primetime lineup during both its fall and spring cycles. The network has used the singing competition to launch original series like The Blacklist and most recently Blindspot. The 2016-17 TV season will be the first without The Voice's main rival, American Idol, which will leave the air in April.
