Rapper 50 Cent has vowed to stop joking about the alleged altercation between Chris Brown and Rihanna - after seeing a photograph of a badly bruised Rihanna.

Brown was charged with making criminal threats following an incident earlier this month which reportedly left the Umbrella hitmaker needing treatment.

Now 50 Cent, real name Curtis Jackson, had been making light of the alleged fight, even posting an animated video on his website featuring Brown and Rihanna as characters from the video game Street Fighter.

But he has promised to stop poking fun at the supposed altercation after he saw a photo on a website showing Rihanna with a bruised forehead, a swollen nose and a bloody lip.

Meanwhile, rapper Flo Rida has been forced to dump his anticipated collaboration with Brown from his forthcoming album - as a result of the singers' fallout. - Wenn
