Looks like Jessica Simpson is keeping true to her word – and her healthy new outlook on pregnancy.

The star, who's expecting her second child with fiancé Eric Johnson this summer, decked out her baby bump in an all-black ensemble Thursday, looking fit and trim while out in L.A.

The Weight Watchers spokeswoman is already mom to 9-month-old Maxwell Drew and has spoken out about gaining more than 50 lbs. while pregnant with her daughter.

"Being healthy has become a part of who I am, which is great timing because I'm having another baby," the expectant mom said late last year. "I feel like I'm on top of the world."
