'(Peep the babies heading to get more buckets of water to fill in the hole they dug up for Bubby to lay in) #momanddad #beachbabes #familytime #sunshinestateofmind,' she continued, adding a crying laughing face emoji.

Decker showed off her taut tummy and ample cleavage in the two-piece that featured a brightly colored swirl pattern. Her sculpted legs were on full display in the bikini's high-waisted bottoms.

She accessorized with a couple of delicate gold necklaces and donned a pair of gold-rimmed square sunglasses. Jessie's golden-streaked hair was pulled back into a low ponytail.
