She’s the proud mommy to three beautiful children, and now it seems Jennifer Garner may be pregnant with her fourth.

The “13 Going On 30” actress showed up at a Pacific Palisades, California school this morning (July 24) sporting a loose-fitting navy blue sweater as she took her daughter Seraphina to class.

And when she emerged with her eldest kiddo Violet, Jennifer showed what appeared to be the beginnings of a baby bump.

Meanwhile, Garner was named the new face of Max Mara’s campaign, and it seems she’s already a big fan of the luxury label- “My style is pragmatic. I like to wear garments that have a real luxurious texture and feel good against the skin.”

Chairman Luigi Marimotti told press, “Jennifer Garner is a real woman, not a cover girl, not a starlet, and she has different interests, a family and values. She is a real woman and embodies the Max Mara woman, she perfectly reflects our image.”
