Jennifer Garner Covers 'InStyle' January 2012

Jennifer Garner looks cozy in a Donna Karan Casual Luxe sweater coat on the cover of InStyle‘s January 2012 issue, on newsstands Friday (December 16).

Here’s what the 39-year-old actress and mama-to-be had to share:

On her marriage to Ben Affleck: “I don’t know how or why it works as well as it does. Honestly, I would do anything for that man, because I know it’s not taken for granted.”

On pregnancy: “I wish I was one of those cute pregnant girls who wear skinny jeans throughout their pregnancies. But I just gain weight. I’m trying really hard to be mindful, but when I’m making the kids mac and cheese, I want it badly.”
