Brad Pitt, John Mayer, films and double standards discussed

Approaching 40 never looked so good as Jennifer Aniston's latest magazine cover.

The "Marley & Me" star wears nothing but a patriotic necktie and a smile on the cover of January's GQ and shows plenty more skin for the interview inside.

Aniston, who turns 40 on Feb. 11, comments, "It felt really good to be that comfortable with myself -- and to lie on men as furniture," referring to the inside photo of her sprawled among scantily clad, buff men.

"I still can't wrap my head around how old I'm going to be," says Aniston. "I feel more comfortable today than I ever did in my twenties or early thirties. I am more at peace in my mind and with my body."

She's all about celebrating her age and sexuality, especially in a new film she's working on called "Pumas," which she describes as "sort of a female 'Wedding Crashers'" about two "aspiring cougars." The movie sounds like it could help usher in a new age of female "bromance" comedies, not to be confused with chick flicks.

"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...'

"Look, I think all women on some level just want to rage against the machine," she continues. "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."

In the not-so-revealing interview, Aniston discusses the men in her life: boyfriend John Mayer, "I am not having his baby. And I have not popped the question" and ex-husband Brad Pitt, "We don't not talk."

As for Angelina Jolie, Aniston tries to play it off, but there's really no contact or positive feelings towards the Other Woman.

"The funny thing is, people don't realize we all go away to The Hamptons on the weekends," she jokes. "That'd be hysterical: I've got Zahara on my hip, and Knox..."

The issue hits newsstands on Dec. 23.

Aniston stars opposite Owen Wilson in "Marley & Me," which opens nationwide on Christmas Day, and in the ensemble romantic comedy "He's Just Not That Into You," which will be released in February.
