OK, maybe the embattled ex- View-er is nuts after all. The New York Post says Oprah wanted to have her on her talk show - which makes best-sellers of books overnight, I needn't remind you - to discuss Celebrity Detox, O'Donnell's scathing new tell-all. And Rosie went all Amy Winehouse on her and said no, no, no! "Rosie has always been booked with Diane [Sawyer]," says her rep. "We gracefully declined Oprah's offer. I'm sure Rosie will do Oprah's show another time." After this, I kinda doubt it. Look how long she stayed mad at Letterman.
