Jennifer Aniston is still all fired up four years after her split with the dashing Brad Pitt – and is baring all before she turns the big 4-0. Wearing nothing but a necktie for the January cover of GQ, an inside picture shows Aniston sandwiched between two seemingly naked men. Inside, there’s a candid interview in which Aniston calls her relationship with Angelina Jolie and Pitt an "insane Bermuda Triangle."

She jokingly continues: "The funny thing is that people don’t realize we all go away to the Hamptons on the weekends … No. But can you imagine? That’d be hysterical: I’ve got Zahara on my hip, and Knox …" she said, referring to two of Jolie and Pitt’s six — and counting — kids.

But she says she and Pitt do speak from time to time: "When there’s something to congratulate or celebrate, there’s an exchange. But there’s no charge on it."

More of what she said in the interview:

On looking jaw-dropping at 39: "I feel more comfortable today than I ever did in my 20s or early 30s," she said. "I’m healthier. I’m more at peace in my mind and with my body."

On her on-again boyfriend John Mayer: "Honestly, did not know much about him before I met him. I’d heard … you know, uh, ‘Your Body’ – that song. But what I can say is that I had no idea what an extraordinary musician he is. And it’s just great to sit and be witness to that. It’s kind of like, Whoa!"

On the rumors surrounding pregnancy and marriage: "I am not having his baby. And I have not popped the question."

On Aniston’s current work on the film, "Pumas," which she calls "sort of a female ‘Wedding Crashers’" about two "aspiring cougars": "It is so a comment on the sexual double standard, and what’s been ironic is how hard it’s been to get this movie made," she says. "Studios want it, but they are afraid of Middle America. They’d want to change it; they’re saying, ‘Oh, you can’t do that, people just can’t imagine you …’"

On female movie roles in Hollywood: "Look, I think all women on some level just want to rage against the machine," she says. "There are too many movies out there that don’t empower women, movies in which their only way of being happy is finding a man. And you know, that’s not my favorite theme."

The January issue of GQ hits newsstands December 23. Excerpts of the cover story appeared in the New York Post, People.com and JustJared.com.

Aniston isn’t the only piece of the "Bermuda Triangle" running her mouth. Brad Pitt recently spoke to Rolling Stone. In the interview he says that he and his partner Jolie don’t fight. Pitt says, "I don’t want to waste time being angry at someone I love." 

How cute. This may push Aniston over the edge. It may compell her to fling off her necktie.
