Chris Brown has fled the Twittersphere following a foul-mouthed exchange with a female comedian.

The R'n'B star deleted his account on the microblogging site after a war of words with Jenny Johnson over his apparent lack of remorse since his 2009 assault on Rihanna.

Things kicked off after Brown tweeted a photo of himself with the caption, "I look old as f---! I'm only 23."

An unimpressed Johnson responded: "I know! Being a worthless piece of s--- can really age a person."

Brown, who is on probation after pleading guilty to the attack on Rhianna, responded with a string of expletive-filled rants.

The conversation quickly degenerated with Brown making crude oral sex jokes and Johnson questioning his mother's parenting skills.

"Take them teeth out when u sucking my d**k Hoe," Brown told Johnson.

He then added: "Mom says hello... She told me not to s**t in ur mouth, wanted me to s**t right on the retina."

Johnson eventually ended her side of the conversation,saying: "Okay. I'm done. I have zero respect for a person who seems unapologetic for the terrible crime he committed".

Minutes later, Brown deleted his account.

The pair have come to verbal blows before.

In 2010 Johnson retweeted the comment "Call me old-fashioned, but Chris Brown should be in prison", to which Brown replied: "Flirt!"
