Justin Theroux Dubbed "Mr. Jennifer Aniston" In October Issue of 'GQ'

Justin Theroux steams up the pages of GQ's October issue, showing off some serious attitude in a photoshoot for the magazine, which has dubbed him "Mr. Jennifer Aniston." 

Jen's new beau is bearded in the photos, and opens up about women's response to his facial hair.

"Certain chicks dig it; certain chicks don't," he shares, adding, "You establish all sorts of mannerisms with it. Like when you're bored, you can feather your mustache."

GQ notes that after Justin's photoshoot, his beard was gone. Perhaps Jen likes him clean shaven?

In the photoshoot for the magazine, Justin channels Al Pacino's role in 1973's Serpico, paying homage to "the movie's gritty streets and styles."

The interview also reveals another fun fact about Jen's leading man — he has a "dork voice" determined by his "precise enunciation" and word choice in conversation.

What vibe do you get from Justin? Sound off below.
