"Two women coaches is what The Voice needs!" Alicia says in the new trailer. "I'm looking forward to rooting people on and being here for the dreamers like me," she continues. "You're able to hear someone true for who they are, and that's what music is."

Commenting on the new line-up Blake added: "I don't know that we've ever had a shake-up like season eleven."

Describing Miley he said: "She's this great performer. But she also has this ear for music." Displaying her customary swag, Miley said: "If you're rock, you get with Adam, if you're country, you go with Blake. With me, I don't think there's that genre wall. I think if you do country, you could wanna be on my team - Blake," she added.
