'We Can't Stop' beauty Miley Cyrus has continued to raise the bar with her risqué behaviour and last night's unveiling of her Halloween costume is a great example. 

She took to her official Twitter page in the early hours of this morning (October 31) and shared a snapshot of herself, in which she can be seen posing with a lilac wig, very revealing outfit, and nipple pasty, and accompanied it with the caption: "Happy Halllllloweeeen."

In another photograph, she tagged rapper Lil' Kim (pictured below in a similar outfit) so the costume may be an homage to her. Upon seeing the tweet and Cyrus's bold clothing choice, Kim replied publicly and gave her stamp of approval: "Awwww. Look at my baby @mileycyrus tonight!!! Looking GORGEOUS!!! I wish I was there to squeeze your boob :) :) Love U so much !!!! #mytwin."

The former Disney starlet isn't bothered by showing skin as she recently explained that nudity doesn't show vulnerability in the same way that being openly emotional does, so she woud rather be naked in public than cry in front of people:

"For me, nudity has never been something that I've ever tripped about. I don't really see it the way everyone else sees it. I'd rather be naked in front of people than cry in front of people, because I don't like showing weakness and that shows a lot of, like, vulnerabilities."
