Justin Theroux posed for a Serpico-inspired shoot for the October GQ , which hits newsstands on Sept. 20. Jennifer Aniston 's man fits right into the bad-boy scenes; unfortunately, she's not the beautiful blonde on the back of his motorcycle in the shots. Check out Justin's full spread on GQ.com . He's in the magazine to promote Wanderlust, the movie that brought Jennifer and Justin together; though, its release date was just pushed back from October to February 2012. While Justin doesn't explicitly address his high-profile relationship, Jennifer does come up when talk turns to his beard, which he grew for the part. Justin joked about getting used to it saying, "You establish all sorts of mannerisms with it. Like when you're bored, you can feather your mustache." And as for how the ladies feel about his scruff, "Certain chicks dig it; certain chicks don't." These days, however, Justin is rocking a smooth-shaven face for his leisurely afternoons out with Jennifer. Jennifer and Justin have been spotted  going to a few appointments together, fueling rumors of a baby, but for now they're just happy to shack up and take advantage of more downtime before their film hits theaters.
