Miley Cyrus is probably a contender for best celebrity Halloween costume after she dressed as rapper Nicki Minaj for the spooky celebration. Cyrus, 19, donned a leopard bodysuit, a bright yellow wig and a padded derrière, posting a picture of herself on Twitter.

The often unpredictable Minaj has already reacted to the outfit, so did she love or hate it? Well, she told Ryan Seacrest on his KIIS-FM radio show that she would dress as Miley next year in return "I think I'm going to probably go as Miley Cyrus. Because she is going as me and I just saw her picture on Twitter. I could do the short blonde buzz-cut like Miley," she said. The former Hannah Montana star really got into the Halloween spirit this year, also dressing as a spooky looking skeleton for a bash at the Hollywood Roosevelt hotel. 

Though she won all the plaudits for her Halloween outfits, Cyrus has been the subject of controversy this week after she hired a porn star for the video of her new song Decisions. According to TMZ.com, Miley asked adult actress Jessie Andrews to appear in the clip which also features a unicorn, a goat and a woman with "watermelon smashing boobs."
