People.com: Talk about your revealing interviews.

Jennifer Aniston puts on a necktie and leaves the rest in the hamper for a provocative GQ cover and sassy interview that addresses rumors about John Mayer.

"I am not having his baby. And I have not popped the question," the actress, 39, tells January's GQ (on stands Dec. 23).

Aniston also pokes fun at her recent swipe at Angelina Jolie.

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

As for her feelings about Mayer, 31, she says, "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!"

Aniston's currently working on a film called 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..."

It's part of what she sees as a disturbing problem 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."
