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.

Meanwhile, the Maroon 5 guys got all dressed up for the occasion. Can you guess which member was Skrillex?

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!

Katy Perry took part in the fun and portrayed Jane from Daria.

And although Lady Gaga seems to dress up every day of the year, she makes no exception for Halloween.

Rita Ora had some fun while she was stuck in New York. And we must say, she makes a scary Jason.
