Jessica Simpson is flaunting it while she's got it.

The 32-year-old pop star and Weight Watchers spokeswoman showed off her trim figure in a photo she posted on Twitter Thursday, posing in a red beach cover up and a cowboy hat. Her caption: "Fun in the sun," a reference to her holiday trip to Hawaii, where she's vacationing with fiance Eric Johnson and daughter Maxwell. Simpson's extended family - mom Tina, sister Ashlee, and Ashlee's son Bronx - also joined in on the beach jaunt.

Though she's soaking up the sun now, it's been a busy week for Simpson. On Christmas Day, she revealed that she's expecting her second child. While she will not continue her Weight Watchers diet during her pregnancy, she'll continue to appear in ads for the weight loss company that signed her on earlier this year.

"There have been no changes to our business agreement with Jessica," a representative for Weight Watchers told on Wednesday. "Jessica's successful weight loss prior to becoming pregnant will be featured in Weight Watchers' new 'Expect Amazing' advertising campaign, including a spot with her sharing the happy news."

The 30 second ad in which Simpson says she's pregnant, posted Wednesday morning on YouTube, was shot at the same time as her most recent "Expect Amazing" commercial, where she shows off her 50 pound weight loss. The ads are scheduled to air through winter.
