Baby Affleck has scored his first magazine cover!

Well into her third pregnancy, which is rumored to be the celebrity couple's first boy, Jennifer Garner exudes that maternal glow in an irresistibly cozy Donna Karan Casual Luxe sweater coat for InStyle's January cover.

Naturally, family comes first for the actress. And Garner credits husband Ben Affleck for providing the support system she and their children need.

“I don’t know how or why it works as well as it does,” she tells the magazine. “Honestly, I would do anything for that man, because I know it’s not taken for granted."

With her brood growing, Garner says it's more difficult to maintain a glamazon image. (For the record, her Andreas Sjödin-lensed photo shoot sees her killing it in smoky eyes and a Vionnet silk dress, bump and all.)

“I wish I was one of those cute pregnant girls who wear skinny jeans throughout their pregnancies,” says Garner.

“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.”

Don't let us stop you, Jen ... though you might want to avoid looking at Jessica Alba's post-baby bodysuit fashion spread. Talk about pressure!
