Looking the sexiest we’ve ever seen her in the January 2013 issue of British GQ, Jessica Chastain may have you wondering well who the hell is Jessica Chastain. For one, we know you’ve seen her in the commercials for the controversial Osama man hunt film Zero Dark Thirty, out 1/11/13. You’re not alone in thinking she just recently stepped out onto the Hollywood scene, but in fact, Ms. Chastain has been in the biz since childhood, though never afforded the meaty roles to propel herself higher. You might of missed her in The Help (chick flick), we’re sure you missed her in The Tree of Life (like watching a screensaver) but if you missed her in Take Shelter (sleeper hit), we feel sorry for you. Although she received an Oscar nom for The Help, Chastain hasn’t much else to her resume besides TV shows, plays and some dancing. But for this issue of GQ, a ginger never looked better in bed, and from what we hear, we’re sure she killed it in her Zero Dark Thirty role.
