The comedian was involved in an altercation on Twitter with the R&B singer yesterday (November 25), taking him to task for his assault on ex-girlfriend Rihanna and labelling him as "worthless".
Brown responded with a number of aggressive tweets, telling her to "suck his d**k" and saying he would like to "s**t on her retina". He then posted: "Just ask Rihanna if she mad??????", before deactivating his account.
Billboard reports that Brown's decision to leave Twitter led to his fans sending thousands of abusive tweets to Johnson, that included death threats.
One user tweeted: "@JennyJohnsonHi5 Stfu bitch honestly, i wanna sit on your face and stab 1235 needles in your eyeball, you son of a motherless goat. #bushpig", while another posted: "@JennyJohnsonHi5 who the f**k are you? what the f**k did you do with Chris Brown? GIIIIRL, I HOPE YOU KNOW.. I WILL KILL YOU."
The tweets continued throughout the day as more became aware of Brown's exit from Twitter and became increasingly ferocious, with user Shut up ¡BITCH! writing: "@JennyJohnsonHi5 I would not wish anyone death but I hope you die", and another account titled Twittter Legend™ tweeting: "@JennyJohnsonHi5 I'M GONNA F**KING RAPE & KILL YOU OLD WHORE F**K".
Johnson herself drew the attention of her followers and the official Twitter account toward the abusive tweets, before joking: "I hope Bono writes a song about me."
