She's Preggers - We TOLD You!

We caught up with Jen today at a friend's house in Santa Monica, looking, well, pregnant!

Jen's bump isn't extra helpings of desert or French fries and burgers -- it's a baby, y'all!

Us Weekly reports Garner's former Alias co-star Victor Garber pulled a Jack Black and confirmed the news to Us saying "She is five months pregnant. They are very happy."

We called it back in March!!!
