Chris Brown has closed his Twitter account following an explosive online row.

Chris Brown's twitter enemy has no plans to apologise to the singer.

The 'Don't Wake Me Up' singer - close his twitter account following an explosive online row with Jenny Johnson after she made a comment which referenced him assaulting his on/off girlfriend Rihanna in 2009 last week - but the US comedian doesn't regret their explosive online row during which she called the 23-year-old an “ignorant” “piece of s**t”.

In a new blog post for GQ magazine, she said: “This is not an apology. I assumed a couple of days would pass and other things would happen and our little spat would be yesterday's news.

“I won't say I regret what I did, but I will say I have learned from it. I chose to turn a lazy Sunday watching football with my husband into a total s**tstorm.

“I never thought I'd see the chicks on 'The View' attempt to break down our interaction on twitter.

“My twitter account is meant to be funny. While there are truths behind a lot of the things I write, in no way, shape or form are they meant to be seen as anything other than the words of a comedy writer, in 140 characters or less.”

The row started after Chris joked on twitter: “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.

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.
