JESSICA Simpson has confirmed she is pregnant again.

The 'Fashion Star' mentor took to her Twitter page on Christmas Day (25.12.12) to post an image of her daughter Maxwell Drew, seven months, on the beach in Hawaii with the words 'Big Sis' written in the sand following over a month of speculation that Jessica and her fiance Eric Johnson were already expecting their second child.

Captioning the picture, she wrote: "From my family to yours."

After giving birth to Maxwell on May 1, Jessica was named the face of slimming brand Weight Watchers and worked to lose the 60lbs she gained during her pregnancy.

And despite the fact she is already expecting again, she will remain the face of the diet company.

They tweeted: "Congrats to @JessicaSimpson, Eric and big-sister-to-be Maxwell! Your WW family is so thrilled for you. What an amazing year you've had! (sic)"

The firm have also announced they will continue to run ads promoting the 32-year-old beauty's 50lb weight loss, as well as pushing a new commercial in which she announces her pregnancy.

Praising her "successful" weight loss, the company added: "Jessica will not be following the programme during the pregnancy while her weight and well-being are monitored by her obstetrician."
