(Cover) - EN Showbiz - Justin Theroux hints that partner Jennifer Aniston prefers him clean-shaven.

Justin and Jennifer began dating after they met on set of their upcoming film Wanderlust. Justin had to grow a shaggy beard for his role as cult leader Seth in the comedy. He grew quite an affinity for his facial hair and thoroughly enjoyed playing with it.

"You establish all sorts of mannerisms with [your beard]," Justin explained to GQ magazine. "Like when you're bored, you can feather your moustache."

Justin loved plucking his facial hair, but is not convinced that girlfriend Jennifer is as enthusiastic about it as he is.

When asked about whether or not Jennifer was into the grizzly bearded type, Justin was uncertain.

"Certain chicks dig it; certain chicks don't," Justin declared.

Justin and Jennifer moved into a quaint house in the Hollywood Hills together last month and are rumoured to be planning a private wedding.

The pair's film Wanderlust will be released in the US in February 2012. (C) Cover Media
