Rihanna was crying over her ex-boyfriend Chris Brown on Oprah's Next Chapter. Keep in mind that Chris has been sleeping with Karrueche Tran for the past few years. Translation: Rihanna is insane! During RIhanna's interview, she said that she still loves Chris. Joan Rivers took to Twitter to give her 2 cents.

Rihanna also told Joan to "slap on some diapers." Sigh. Yes Rihanna, Joan is the problem. You need to move on. Keep sexting Robert Pattinson.
