Jessica Simpson Heads to the Gym on First Day Out as a New Mom to Baby Maxwell

Post-baby Maxwell, Jessica Simpson stuck to her Weight Watchers spokeswoman deal and headed to a private workout session in Los Angeles

Let's get this out of the way immediately: We are not slamming Jessica Simpson's post-pregnancy knockers.

Repeat: Not. Slamming. The knockers.

In fact, we're very impressed with the soon-to-be-Mrs. Eric Johnson, and not just because this is Jessica's first public outing since she brought forth a little girl named Maxwell...

No, we're impressed because she managed to tame those Grand Tetons long enough to get in and out of a car, plus—from what we hear—hold down a workout at a private gym in Los Angeles.

Mama Jess is a new spokeswoman for Weight Watchers, and it looks like she's taking the gig seriously, sporting an exercise-friendly ensemble that included a black cardi and roomy shades.

We also love that the former Mrs. Nick Lachey is looking after her own safety now that she's a mom—those are two very serious front-seat airbags.

In a good way!

Carry on.
