The 45-year-old actress dazzled at the Los Angeles premiere of her new film “Horrible Bosses 2,” even though she recently made a huge transformation from her fit and trim figure to not-so-fit appearance for the filming of her another upcoming movie “Cake.”

Jennifer stated that she simply “didn’t work out for two-and-a-half months” in order to prepare for her role in “Cake,” so, how did she get back to Slim Town so quickly?

Not Easy

“It’s not so easy coming back, let me tell ya! We’ve got a ways go, but it puts you in a different state of mind not to be physical and not take care of yourself,” the actress revealed at the premiere.

Jennifer underwent a total make-over for the worse in order to play Claire Simmons, a woman who ends up having a relationship with a widower after becoming utterly fascinated with his wife’s suicide.

The Hollywood A-lister is already said to maybe have earned an Oscar for this difficult role, but let’s not rush with any speculations just yet.

Dr. Julia Harris

Despite having “loved every second” of her complex role, Jennifer made sure she gets her precious trim figure back as soon as possible since “Horrible Bosses 2” waited just around the corner.

“I had to go to a job the day after I wrapped for my hair company and I just sort of had to snap back into businesswoman mode. I was actually ready to let her go, honestly, and felt quite satisfied at the end.”

“I couldn’t wait to come back,” she said about reprising her role as Dr. Julia Harris, a sex addicted dentist and a horrible boss. “I loved the first one so much. It’s a raunchy little girl to get and come back and play. We all sat in a circle and tabled a bunch of ideas, like how to make it as good, if not better.”

“It was just fun, a great collaborative effort. We all love each other and we all know each other, and with those three guys (Day, Bateman and Sudeikis), it’s like comedy magic.”

“Horrible Bosses 2” hits big screens next week.
