The "Wrecking Ball" hitmaker pulled back her tuxedo dress to expose her nipple for the camera.
She then sat on a chair and spread her legs as Scout and Tallulah pulled equally seductive poses in the background.
Cyrus's friend Mert Alas shared the photographs on his image-sharing website Instagram page.
Meanwhile, Scout flashed her bosom as she lay across a table, and Tallulah flaunted her curvy rear for the camera.
Alas captioned the photograph: "@buuski @mileycyrus Can't take it!! Wont take it #LA #leavemyroom."
In another photograph, Cyrus stands in front of a mirror and pulls her dress to one side to expose her breast while sticking her tongue out.
He wrote: "Now @mileycyrus #wokemeup".
