The former Disney Channel star went glam for the Top 12 live show of the NBC singing competition, wearing a vintage Bob Mackie strapless fitted ankle-length black gown with gold sequin embellishments that sparkled for the cameras.
Posing in The Voice‘s iconic red chair, Cyrus, 24, was all smiles. She accessorized her look with a matching gold clutch and dazzling jewlrey — including a diamond necklace, diamond and black stone drop earrings, a matching diamond and black stone bracelet and series of coordinating rings.
“Vote for team Miley,” the blonde beauty said after blowing kisses in an Instagram video that showed off her dress’ glimmering effects.
She gave a full length view of her look in another Instagram video, this time modeling her gold platform heels.
Later, Cyrus couldn’t help but make a jab at Shelton and his recent headline-making title.
“I am live with the Sexiest Man Alive,” said in a video on Twitter, panning the camera to show Shelton, 41, sipping from a black Solo cup. “No one knows more about being sexy than me! Sorry Blakey. Love ya!”

Cyrus might be teasing Shelton, but he was the one mocking his Voice rival Adam Levine when he won the title earlier this month.
“I can’t wait to shove this up Adam’s ass,” Shelton told PEOPLE, teasing Levine, who was PEOPLE’s 2013 Sexiest Man Alive. “As proud as I am and honored that you guys asked me, that’s really the only thing I care about.”
He went on to say that the new title is “like a confirmation” that he’ll enjoy for the rest of his life.
“It’s going to be used in every conversation, whether it’s at The Voice, or at the feed in Tishomingo, Oklahoma, or in a conversation with a doctor,” Shelton said. “When [people] would say to Adam, ‘Mr. Sexy,’ you’d always see him go, ‘Well, awwww…’ If you say that to me, it’s going to be, ‘You’re damn right, I’m Mr. Sexy! I’ve been ugly my whole life, if I can be sexy for a year, I’m taking it. I’m taking it.”
The Voice airs Mondays and Tuesdays (8 p.m. ET) on NBC.
