Jennifer Aniston has never appreciated people prying into her personal life -- least of all Katie Couric, who hosts her own syndicated daytime talk show. During a July 31 appearance on E!'s Chelsea Lately, Aniston dissed the 56-year-old TV personality and debunked a recent tabloid rumor about life with Justin Theroux.

Aniston's BFF Chelsea Handler began by reading an except from a recent magazine article which claimed the couple are nudists: "Jen's started to embrace her curves at home since longtime lover, nudist Justin, has persuaded her to join in on the fun," the comedienne read. "She was hesitant at first but now she finds it extremely liberating and they spend entire days at home without any clothes on and even cook naked."

Theroux's fiancee rolled her eyes and asked, "What are you reading? Star magazine? We don't walk around nude, darling."

Handler then told Aniston, "I've seen Justin nude, I hope you know that." The We're the Millers star laughed and replied, "Yeah, well, that's because you barge into places you shouldn't be. But he's comfortable enough in his skin." In regards to the Star story, Aniston clarified, "That's not true. It's B.S."

Handler then admitted to Aniston that it's difficult being friends with someone so famous. "Katie Couric was asking me on her show about your wedding and I had to act like I didn't even know you were engaged because I didn't know that was out," she explained. "Then she was like, 'Well, everyone knows about it!' So, I felt really stupid."

Clearly annoyed, Aniston, 44, asked, "What's Katie Couric? Is she a legitimate journalist? Is she getting tabloidy? Wasn't she on the Today show?"

"She was on the Today show," said Handler, who accompanied Couric to the White House Correspondents Dinner in May 2010. "She got a demotion to her own show."
