Justin Theroux joined Jennifer Aniston for a special screening of her new feature Cake in NYC on Sunday. The pair kept the night fairly casual, with Justin choosing to skip the red carpet and Jennifer posing with her costar Mamie Gummer. Jennifer has been earning rave reviews for her performance in the indie flick, in which she plays a mourner suffering from chronic pain. She did admit that she responded to the news of early Oscar buzz "awkwardly and stutteringly" but that she's also "flattered" by the attention. Aside from Cake, Jen has been busy promoting her other film, Horrible Bosses 2. Last week, Jen jetted to London to premiere the flick with her costars Jason Sudeikis and Jason Bateman, although Justin skipped the red carpet fun for that event as well.
