Have you always wondered why Brad Pitt and George Clooney are consistently thought of as the biggest studs in Hollywood? New research from the University of Michigan relating to aggression, status, and sex might help explain. When social status or sex are on a man’s mind, it causes them to act aggressively so as to maintain his cred, according to assistant professor Vladas Griskevicius. But these too attack triggers are linked: “Across different cultures and time, the higher status men have, the more sex or better-quality partners they may have,” Griskevicius said.

While us gals are pulling on tights and wrapping scarves around our necks to warm ourselves during the cold months, guys can get nature to help by growing out their facial hair. We’re big believers in scruff, but sometimes guys like to get a little experimental. After all, for them, facial hair is like an accessory. If your boyfriend has stopped shaving in hopes that he’ll have a woolly beard in a few weeks, check out the facial hair of Brad Pitt, George Clooney, Jake Gyllenhaal, and Adrian Brody below so you can provide some guidance. Or just look at the manly faces and drool.

After the rough year she’s had with her breakup with Italian businessman-turned-criminal Raffaello Follieri, Anne Hathaway could use some good old-fashioned fun.  And what’s more fun that flirting with a new man? Some of our suggestions, after the jump.

Brangelina just had twins and the magazine covers of OK! and Star are at it again, claiming that Brad’s ex, Jennifer Aniston, is desperate to not be far behind on the procreation bandwagon. While Aniston’s rep denied the rumor today, we still find the story to be pretty messed up.  First of all, Jennifer went from being America’s Sweetheart to America’s #1 Cougar in the span of just a few years. And sure, she’s headed straight for the big 4-0, but we didn’t see anyone flinch when 50-something bachelor George Clooney went monogamous with Sarah Larson a few months ago (albeit just for a bit).  No one was putting him on the cover of their trash mag claiming he wanted to settle down and spawn. Not every lady’s biological clock is ticking.

As women wait longer to have babies, complications become more common, and now a new study says that men over 35 can contribute to these pregnancy problems. In intrauterine insemination, the woman’s age was closely associated with a decreased pregnancy rate and miscarriages, according to Dr. Stephanie Belloc of the Eylau Centre for Assisted Reproduction in Paris. And when the men were over 35, there also were increased miscarriage rates, most likely due to DNA damage that comes with age. So, if you and your guy want to have babies later in life—or if you were planning on bedding George Clooney—Dr. Belloc suggests you try in vitro fertilization. [EurekAlert!]

Have you ever dreamed that you slept with your father? Or rode a mechanical bull while a coworker watched? We have and were disturbed for months. Fortunately, dreams don’t always mean what you think they do, and having sex with your father is nothing to worry about, so long as it only happens in your subconscious. Here, we ask psychologist Veronica Tonay, Ph.D. to decode your crazy dreams each and every week, so that you can sleep at night, and dream some more.

THE DREAM IN QUESTION: I had a dream Brad Pitt and George Clooney made me their sidekick. George wanted to go to IHOP for pancakes. They tried to figure out the back way to get in so paparazzi wouldn’t catch me and take photos of me as their “lady friend.” I didn’t like the dress I was wearing. We arrived at the back entrance of IHOP. I was wrapped around the motorcycle with my crotch pressed into Brad’s back. It was more me and Brad, and George was nearby. I didn’t really care about George. I didn’t mind the paparazzi taking photos of me though. My hair was windswept. I looked fierce, storming towards the entrance in my boots and my wrap dress, feeling tiny between these two, big men. Brad kept rubbing the small of my back. It was a GLORIOUS dream. —Stealing Angelina’s Husband, New York, NY

“Rita Hayworth gave good face.” So the lyrics to Madonna’s “Vogue” states, but even science agrees. A new study by the U.K.’s Durham, St. Andrews, and Aberdeen Universities, has just come out linking facial features to romantic desires. Nearly 700 heterosexuals were asked by researchers to rifle through photos of men and women in their 20s and make snap judgments about the subjects sexual habits—whether they were in it to win it or just a one-night stand. Wide eyes and big lips on women were shown to signal interests in short term entanglements, like the late, great example, Hayworth, who had five A-list husbands, including a prince. For men, broad jaws, pronounced noses, and slight eyes inferred they were straight up players, like lady’s man George Clooney. On the other hand, softer features showed a softer side for both sexes and more potential for long-term relationships. Could your face really reveal your heart’s desire? When researchers compared the recorded first impressions to the actual sexual attitudes of the subjects in the photographs, they found 72% of the participants had accurately assessed the pictured person’s romantic behavior.
