Jessica Simpson’s slender post-baby body photo shared by singer

In the setting of a splendid sunset, wearing a white shirt, jeans and cowboy boots, Simpson is all smiles as it is obvious how quickly he returned to her pre-pregnancy body figure.

The beautiful singer took to Twitter on Friday and posted the pic with the message: “Couldn’t stop smiling on set for my new @weightwatchers campaign today! #happy.”
