The actress is barely showing, but she was definitely glowing as she stepped out, showing her tiny baby bump for the first time in public.
Jessica's baby bump made its debut while she was out for a walk with her two dogs in Los Angeles on Friday. It was pretty covered up under a few layers of workout clothes, but it's definitely there!
Us Weekly was the first to break the news that Jessica and Justin were expecting last month and while the couple has been quiet about it, an insider told the site, "Right now they are just enjoying the news for themselves...They just want a happy baby."
The 7th Heaven alum and former 'N Sync-er dated on and off for about five years before finally tying the knot in October of 2012.
