Chris Brown attended a Halloween party hosted by Rihanna Wednesday night at Greystones Manor in West Hollywood.

Rihanna seemed to be dressed as her favorite plant, as she wore a green gown and carried a bouquet of what looked to be a replica of marijuana leaves. Rihanna has never been one to hide her love of marijuana, often tweeting pictures of herself smoking weed to her followers.

Meanwhile, Chris Brown was dressed as an armed Arab. Brown is not one who is new to controversy, and along with the picture he posted on his twitter account with he and his friends dressed as Arabs carrying military guns, he had the caption, “Ain’t nobody [expletive] with my clique!!!!” a reference to a single Kanye West has which is titled, “Clique.”

More than 3,000 of Brown’s followers retweeted the picture.

A source revealed to Hollywoodlife that during the party, “Rihanna was showing such desperate signs [for Chris].She had her hand around him and he was eating it up. Every time she stood up, she would rub his head as if he were a little puppy.”

Also in attendance at Rihanna’s Halloween bash was reality star Evelyn Lozada, who recently divorced disgraced NFL star Chad Johnson. She wore a red wig, dressed as Ariel from ‘The Little Mermaid,’ while her daughter Shaniece wore a provocative black outfit paired with a black face mask.

Paris Hilton also enjoyed the festivities at Greystones Manor, dressing up as Batman’s counterpart Robin, in a bustier and small green skirt. Comedian Kevin Hart came dressed as a character from the 1970s in platform shoes and an afro.

Just earlier this week, Brown also attended a Halloween party that his ‘ex’ girlfriend Karrueche Tran was at, which was also at the Greystone Manor.

Tran dressed in an Oriental style dress as Brown wore a baseball jersey and black and white makeup, resembling a ghoul.

Brown and Tran left the party in separate cars, but that is certainly not going to end the rumors of their being a continuous love triangle between Rihanna, Chris Brown, and Karrueche Tran.
