In the picture, posted on her Twitter page on Thursday, December 27, the 32-year-old singer and fashion businesswoman shows cleavage while wearing what appears to be a red bikini top and matching, loose-fitting frock. She is smiling and sitting on a seat in a furnished room with a Christmas tree in the background.

"Fun in the sun..." she Tweeted.

Simpson and her fiance are spending the holiday season in Hawaii.

"Aloha...," she Tweeted a day earlier, alongside a close-up photo of the two smiling and standing on a beach.

Two days earlier, on December 25, Christmas Day, Simpson posted on Twitter a photo of her and fiance Eric Johnson's daughter Maxwell Drew, dressed in a red and white striped onesie, sitting on a patch of sand with the words "BIG SIS" scrawled in it, surrounded by leaves.

Her rep confirmed to OTRC.com that the singer is pregnant. The singer's daughter was born almost eight months ago, in May.

Simpson became a spokesmodel for the weight loss and diet company earlier this year and a first ad featuring the singer was released in September, more than three months after she gave birth to her daughter. The commercial featured only a close-up of her face and shoulders and did not show her body.

A new ad was released after her Twitter announcement about her pregnancy and shows the singer in a full body shot, wearing a plaid shirt over a black top and blue jeans.

"This year is all about new beginnings for me. I lost over 50 pounds on Weight Watchers and did not have to be perfect to do it," Simpson says in the ad. "Being healthy has become a part of who I am, which is great timing, because I'm having another baby. I feel like I'm on top of the world."

Simpson had been criticized by many people online over her weight gain during her first pregnancy, which some said was excessive, and over her figure in the weeks after giving birth. She signed a multi-million dollar deal to become a spokesmodel for Weight Waters and debuted a slimmer figure at Dillard's at International Plaza on November 17. It is unclear if she will continue to film ads for the company! while pr! egnant.

Simpson, who is 5'4" tall, has said in the past that when she posed nude and pregnant on the April 2012 cover of Elle Magazine, she weighed "like 170 pounds."
