Singer Miley Cyrus was seen exposing her bosom during an impromptu photoshoot with Bruce Willis' and Demi Moore's daughters Scout and Tallulah.

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".
