It was all about Jennifer Aniston on Thursday when she attended the premiere of Horrible Bosses 2 in LA. She showed off her killer legs in a black-and-white Zuhair Murad dress as she posed on the red carpet alongside her costars Christoph Waltz, Jamie Foxx, and Jason Bateman. The actress has been dividing her time between promoting two very different films — the Horrible Bosses 2 comedy and the much more serious Cake, which is already earning the actress Oscar buzz. Jennifer underwent a dramatic physical transformation for Cake, revealing that she worked with minimal makeup (excluding a fake scar that was created on her famous face) and that she "didn't work out for two-and-half months" to soften up her slim shape. However, Jennifer admitted that it was hard getting back into her intense fitness regimen: "It's not so easy coming back, let me tell ya! We've got a ways to go, but it puts you in a different state of mind not to be physical and not take care of yourself."
