Bret Michaels Tells Miley Cyrus, 17, to "Get Undressed" in Song

Miley Cyrus' musical followup to "Party in the USA"?

Singing backup for Bret Michaels -- who commands her to "slowly get undressed" --in an eyebrow-raising love song.

In the just-released rock-country ballad "Nothing to Lose," Cyrus, 17, croons along with the former Poison frontman, 46. Michaels provides lead vocals on the song, which describes an anguished romance.

"We both know better than this," he trills, "still we can't resist...Slowly get undressed."

The chorus describes two lovers tussling in the "darkness": "Won't you fall down on me/So close I can feel you breathe/Tonight in the darkness with nothing to lose/If the truth is all we can see/If I fall for you, could you fall for me?"

Cyrus' next gig is a starring role in the movie The Last Song, out next month, co-starring her real-life love Liam Hemsworth, 19.
