Simpson is becoming famous for her holiday confirmations. On Halloween 2011, she posted a photo on her website of herself dressed as a mummy with the caption, "It's true — I'm going to be a mummy!"

Simpson, 32, and fiancé Eric Johnson welcomed Maxwell Drew just eight months ago.

The Fashion Star mentor was open about her struggles with losing the 70 pounds she gained during her pregnancy. Simpson announced shortly after Maxwell was born that she was Weight Watchers' newest celebrity spokesperson. Simpson shed 60 pounds within six months of giving birth. Weight Watchers wished the celeb well wishes after learning of her second pregnancy.

"Congrats to @JessicaSimpson, Eric and big-sister-to-be Maxwell!" the company tweeted on Tuesday. "Your WW family is so thrilled for you. What an amazing year you've had!"
