(USA TODAY) -- Chris Brown deleted his Twitter account Sunday after engaging in a vulgar war of words with comedian Jenny Johnson.
MTV reports that the feud began when Brown tweeted a photo of himself with the caption, "I look old as (expletive). I'm only 23." Johnson, who has been ribbing Brown since the singer pleaded guilty to felony assault on then-girlfriend Rihanna, responded, "I know! Being a worthless piece of (expletive) can really age a person."
The exchange continued to go downhill from there and included crude oral sex references and references to Brown's mother.
Johnson ultimately had the last word tweeting, "Okay. I'm done. All I got from that exchange with Chris Brown is that he wants to (expletive) on me ... I have zero respect for a person who seems unapologetic for the terrible crime he committed and shows no signs of changing."
On Monday morning Johnson indicated she had been receiving death threats. She tweeted: "It's alarming how many death threats I'm receiving via @ replies. I encourage everyone, including @Twitter to look through them. Not cool."
It was a busy weekend on social media for Brown.
Rihanna created buzz when she tweeted a photo of Brown shirtless on her bed.
