Instead of showing off her new baby bump, Jessica Simpson kept it under wraps.

Enjoying a romantic stroll along the beach with her fiancé Eric Johnson, the Texas-native donned a cowboy hat and multi-colored tunic during the couple’s Hawaiian holiday on Dec. 26.

Simpson, who gave birth to her first child Maxwell Drew on May 1, has been shedding the pounds (over 50!) with the help of Weight Watchers, where the singer-turned-designer serves as the newest spokesperson for the “Expect Amazing” campaign.

Weight Watchers just unveiled the blonde beauty’s latest video installment for the diet company, confirming that she is indeed pregnant with baby No. 2 — clearly putting a pause on her slim-down plan. Simpson publicly shared the exciting news by tweeting a photo of her daughter Maxwell Drew — next to the words “big sis” spelled out in sand.

As Celebuzz first reported on Dec 19. Simpson had casually revealed that she was pregnant with her second child at her father Joe Simpson’s annual holiday party on Dec. 11.
