Los Angeles - Chris Brown has deleted his Twitter account following an explosive online row.
The Don't Wake Me Up singer entered into a vicious argument with American comic Jenny Johnson after she made a comment which referenced him assaulting his on/off girlfriend Rihanna in 2009.
Chris joked on Twitter: "I look old as fuck! I'm only 23."
To which Jenny replied: "I know! Being a worthless piece of shit can really age a person. RT."

Jenny - who has often made fun of Chris for his assault conviction - was then subjected to a stream of aggressive X-rated remarks from the R&B singer, who took serious offence to her comment.
'Just ask Rihanna'
He answered: "Take them teeth out when u Sucking my dick HOE. (sic)"
She replied: "Your mom must be so proud of you," to which Chris retaliated: "mom says hello... She told me not to shart in ur mouth, wanted me to shit right on the retina. (sic)"

Chris then posted: "just ask Rihanna if she mad??????"
The singer and Rihanna are thought to be an item, despite insisting they are just "friends", and the Diamonds hitmaker even posted a picture of Chris lying topless on her bed on Sunday.
'These bitches crazy'
Jenny finally had enough of the abuse and posted two final tweets, saying: "Okay. I'm done. All I got from that exchange with Chris Brown is that he wants to shitt and fart on me.
"I have zero respect for a person who seems unapologetic for the terrible crime he committed and shows no signs of changing."
Chris tried to calm his shocked followers down before deleting his Twitter account, calling Jenny "immature" and "crazy" and claiming he wasn't bothered by the bust-up.
He posted: "Back to life... To teambreezy... Know that I'm not upset. Just felt like entertaining the ignorance. These bitches crazy. Further proved my point of how immature society is. #CarpeDiem. Catch me in traffic. (sic)"
