Leave it to Jessica Simpson -- now Jessica Johnson -- to make a one-piece look super-sexy.
Jessica took to Instagram on Tuesday, July 15, 2014 to show off her svelte bikini bod poolside, while also announcing that she's officially taking the last name of her husband Eric Johnson.
"Jessica Johnson" she wrote simply.
Jessica, 33, and Eric, 34, tied the knot over the Fourth of July weekend at San Ysidro Ranch in Santa Barbara, Calif.
The black-and-white snapshot is the latest evidence that Jessica has dropped the baby weight and then some.
