Apparently she really can't stop!

Miley Cyrus has offered a racy sneak peek of her upcoming music video for "Adore You," and it features the never-shy singer writhing around in her underwear and appearing to masturbate. (Hey, at least she's wearing something in this clip?)

Cyrus, 21, posted the teaser (embedded below) to Instagram over the weekend. The full video will premiere on Vevo on Thursday, Dec. 26.
