Joan Rivers sparked the Twitter ire of Rihanna last Friday, when the "Fashion Police" host Tweeted her reaction to the pop star's recent Oprah Winfrey interview, where she shared her feelings about ex-boyfriend Chris Brown.
"Rihanna confessed to Oprah Winfrey that she still loves Chris Brown. Idiot! Now it's MY turn to slap her," Joan Tweeted.
Rihanna didn't mention Joan's Twitter handle, but she appeared to respond, writing, "CONTROL YOUR SPEECH," linking to a photo of a book explaining a Bible passage about offending speech.
But, she didn't stop there.
The singer also took aim at Joan's age, Tweeting, "wow u really do get slow when you're old huh," a comment she later deleted.
Rihanna did keep up a Tweet targeting Joan's bladder.
"Slap on some diapers," she wrote.
Joan didn't back down, and in fact, threw in a plug, in responding to Rihanna.
"Honey, @Rihanna, everyone knows: If he hit you once, he'll hit you again. Read the statistics. PS - Love to have you on Fashion Police," she wrote.
