You’re never too old to celebrate Halloween.

Over the past few weeks we gave you some tips on how to be your favorite musicians for Halloween. It turns out some musicians decided to be each other this year. Here’s a rundown of some of the best costumes. Who pulled it off best?

Miley Cyrus as Nicki Minaj

It’s a look you never thought you’d see but Miley pulls it off well. We wonder how Nicki reacted when she heard the news.

Our other favorite judge on The Voice, Blake Shelton, dressed up as a female musician. We bet his wife had something to say about that!
