Jessica Simpson’s Post-Baby Bum – First Look! (PHOTO)

Who needs old-fashioned motivation when you've got $4 million lighting a fire under your soon-to-be rock-hard bottom?

New mom and Weight Watchers spokesperson Jessica Simpson seems eager to cash in on her pending fortune, as she's already hard at work on her post-pregnancy weight loss regimen, just a month and a half after giving birth to her first child, daughter Maxwell Drew.

Jess was spotted leaving a gym in Los Angeles yesterday, June 12, in a pair of tennis shoes, tight leggings, and a black hoodie.

So how much weight is the 5'3" star expected to lose? Weight Watchers hasn't released a specific number, but a source close to Jessica told Us Weekly that she'll be expected to work out with a trainer at least five times a week.

Fellow diva and new mom Beyonce has already lost a whopping 60 pounds, and earlier this year, Mariah Carey revealed she lost a total of 70 pounds after giving birth to twins.

Although J. Simp is ultimately more concerned with inches than pounds, we'd love to see her back at a healthy 120. When she posed nude for the April cover of Elle magazine, she was already tipping the scale at around 170 pounds.

"I think anybody who's gone through a pregnancy, after they have the baby, it's like, 'I need to do something about this,'" Jessica told People magazine in the June 11 cover story.

"For me, I really want to do something that is a lifestyle, because in the past, I've been known to yo-yo diet."
