Chris Brown Causes Controversy, Katy Perry Goes MTV Retro For Halloween

Hurricane Sandy may have hindered Halloween plans for most on the Northeast, but some celebrities still got into the Halloween spirit dressing up in over-the-top, creative and sometimes controversial costumes.

Chris Brown caused quite a stir after he posted a photo on Instagram of himself with his friends seemingly dressed as Arab terrorists in beards and turbans. Brown completed the questionable look by holding a rifle above his head and wrapping bullet casings around his robe.

"Ain't nobody F---ing wit my clique!!! #ohb," Brown said on Instagram before attending Rihanna's West Hollywood Halloween party.

Yet, not everyone's Halloween costume proved to be controversial, pop star Katy Perry and actress Shannon Woodward opted to dress up as retro MTV animated characters, Daria and her best friend Jane Lane as they attended a party at the Hollywood Forever Cemetery.

"@shannonwoodward You're like my... best friend," Perry tweeted, who is wearing a voluminous black wig and red blazer, with a photo of the two.

Also at the Halloween bash were costars Robert Pattinson and Kristen Stewart, who join MTV tonight for
