Jessica Simpson: Weight Watchers' New Spokeswoman!

Jessica Simpson is the latest celeb to join Weight Watchers!

“The cool thing about the program is that it focuses on healthy habits for the long-term (and I can still indulge in my guilty pleasures every now and then too),” the 31-year-old entertainer wrote on her Facebook page the same day her People cover – with baby Maxwell – debuted.

“I have actually gotten a group of friends together who are going to be doing it with me,” Jess added. “You can join me too and we can share our experiences!”

Other celebs who’ve slimmed down with help from Weight Watchers include Jennifer Hudson, Jenny McCarthy, and Ginnifer Goodwin.
