Soulja Boy, Chris Brown 'row on Twitter'

Soulja Boy and Chris Brown have sparked a war of words on Twitter.

The row started when the 'Crank That' star posted a message boasting that he had more followers on the micro-blogging site than either Brown or rival Bow Wow.

He wrote: "#ListenBitch add @ChrisBrown & @BowWow followers together and you still aint half way f**kin wit me lol (sic)."

Brown then responded by crowing about how much he earns in comparison to either of the young rappers, posting: "@souljaboytellem and @bowwow what yall make in a show i make for an hour at an afterparty... jus sayin."

The spat continued after Soulja Boy fired back: "#ListenBitch if my last tweet offended you I won."

He also challenged Bow Wow to a chart battle, later sending him the message: "lol @bowwow there you go. f**k bank accounts. f**k followers. let's see who new album sell the most 1st week."
