Twitter is a place for the war of words at the moment between Joan Rivers, Kelly Osbourne and Rihanna. After Rihanna’s tearful interview aired in America last week, in which she confessed to still loving Chris Brown, even after he assaulted her, Joan Rivers got angry and tweeted: “Rihanna confessed to Oprah Winfrey that she still loves Chris Brown. Idiot! Now it's MY turn to slap her.” Rihanna, never one to stay quiet, of course replied and said: “Joan_Rivers wow u really do get slow when you're old huh? Slap on some diapers.” Kelly Osbourne who presents a TV show in America with Joan Rivers called Fashion Police, also then got involved. She said: “With the greatest of respect 2 a young lady of whom I love please get a sense of humour @Joan_Rivers paved the way 4 all us opinionated ladies!” Joan Rivers then decided to take a nice approach to Rihanna and said: “Honey, Rihanna, everyone knows: If he hit you once, he'll hit you again. Read the statistics.” She then followed it up with: “PS - Love to have you on Fashion Police!” Well after all that, we think a request to get her on your TV show was a little far-fetched!
