Catfight alert? Appearing on Chelsea Lately Wednesday, Jennifer Aniston mocked Katie Couric, Variety reports. Host (and Aniston bud) Chelsea Handler was talking to Jen about the time Couric asked Handler, during an interview, about Jen's upcoming nuptials. "I had to act like I didn’t even know you were engaged because I didn’t know that was out. Then she was like, ‘Well, everyone knows about it!’ So, I felt really stupid," Handler recalled. Jen's response: "What’s Katie Couric? Is she a legitimate journalist? Is she getting tabloidy? Wasn’t she on the Today show?"
Handler then got even cattier: "She was on the Today show. She got a demotion to her own show." Also on the show that night, Aniston shot down rumors that fiance Justin Theroux has turned her into a nudist. "No, we don't walk around nude," she said, according to the New York Daily News.
