Singer Chris Brown, who has been associated with domestic violence after being accused of beating up his ex-girlfriend Rihanna, would not have dreamt in his wildest dreams that he would receive flaks for his Halloween costume that resembles Arab terrorists but many don't find it funny.

Chris Brown attended Rihanna's Halloween party in West Hollywood dressed up like an Arab terrorist.

"Ain't nobody F--king wit my clique!!! #ohb," he tweeted, linking it to a photo in Instagram that has him and four other friends in the getup of a terrorist.

The 23-year-old singer and his friends were seen with fake beards, turbans, guns, long robs and bullet belts.

However, the photo seems to have not gone down well with some people, terming it as "not funny".

"It's not just a costume. How would you feel if some white chick painted herself black and said, 'I'm dressing up as a black chick for Halloween?' Of course it's only funny if it's not happening to you," read a comment on the singer's photo on Instagram. "F**k you I was a fan until now no wonder everybody hates you disrespectin people religions is beyond disgusting !!! Go to hell p***y a** women better," wrote another.

However, some think that it should not be taken seriously cos it was done for fun.

"Why are people making it bigger then what it is? Hahaha ohhhh gosh Halloween is for fun if you take offense to it then you're doing the most," wrote one. "Yo whoever doesnt think this is funny #SlapYourself," wrote another.

Chris Brown has a supporter in his mother though many chose to criticize him for the costume. She took to twitter to support her son.

"HALLOWEEN IS FOR FUN NOTHING MORE THAN JUST FUN. GET A LIFE PLEASE," Joyce Hawkins tweeted.

Chris Brown was arrested in 2009 for assaulting his then girlfriend Rihanna at a pre-Grammy Awards party. He will remain on probation until early next year for the assault.
