Chris Brown has deleted his Twitter account after a vulgar online exchange with comedian Jenny Johnson.
Jenny says she is now receiving death threats on Twitter from the singer's supporters.
The fight started when 23-year-old Chris posted a picture of himself, saying he looked old. Jenny replied: "I know! Being a worthless piece of (expletive) can really age a person."
Chris fired back with a series of crude sexual jokes and Jenny posted a link to a news story about his 2009 assault on then-girlfriend Rihanna.
Before deleting his account, Chris wrote: "Just ask Rihanna if she mad??????" The on-again-off-again couple has been seen together recently.
Chris had 11.6 million followers on Twitter.
