“Good Morning, America! Going live soon! #weightwatchers,” Simpson captioned the picture in which she looks fit in a black dress that highlights her incredible figure.

In a recent interview, the mom of two, son Ace Knute, 6 months, and daughter Maxwell Drew, 18 months, revealed her secret behind her new silhouette, and that is her children who keep her in a continuous to-and-fro.

“With both kids I’m running up and down my stairs a million times,” she told USA Today in December. “Kids can keep your metabolism going.”

Indeed she looks fantastic!
