Chris Brown back on twitter

Chris Brown has reactivated his twitter account almost one week after deleting it following an explosive row with American comic Jenny Johnson about his assault on girlfriend Rihanna in 2009

Chris Brown has reactivated his twitter account following his explosive online row.

The 'Don't Wake Me Up' singer deleted his account last week after entering into a vicious argument with American comic Jenny Johnson, who had made a comment referencing his assault on his on/off girlfriend Rihanna in 2009.

The 23-year-old singer has yet to tweet anything but his account is now back in working order and still has almost 9.5 million followers.

Chris furiously deleted his account after receiving backlash from the comedian when he joked: ''I look old as f**k! I'm only 23.''

To which Jenny replied: ''I know! Being a worthless piece of s**t 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.

He answered: ''Take them teeth out when u Sucking my d*** HOE. (sic)''

She replied: ''Your mom must be so proud of you,'' to which Chris retaliated: ''mom says hello... She told me not to ***** in ur mouth, wanted me to s*** right on the retina. (sic)''

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 b***hes crazy. Further proved my point of how immature society is. #CarpeDiem. Catch me in traffic. (sic)''

Chris has been extremely ! active on his Instagram during his absence from twitter.

Earlier today (02.12.12) he posted a picture of himself and a scantily clad Rihanna with the caption, ''What would music today sound like if these kids didn't exist?''

The couple are believed to have recently rekindled their relationship despite Chris still being under probation for assaulting the 24-year-old 'Diamonds' singer.
