Jennifer Aniston was on Oprah today to promote her new film Marley & Me (which opens the same day as Brad Pitt's The Curious Case of Benjamin Button ), and Oprah dove right into talking about Jennifer's Vogue cover and interview. Jen said that the cover's quote about Angelina Jolie wasn't completely accurate, but that yes, she felt that some of the shit that Angelina said has been "uncool." She went on to say that she's proud of Brad and his family and the work that he's done in the past few years. She also didn't miss a beat after Oprah asked her if she's dating John Mayer. It was a resounding "Yes!" But she's not pregnant. And definitely not pregnant with twins. Clip above.
