Dressed in head-to-toe black, the new mom headed to a sweat session with trainer to the stars Harley Pasternak— who has sculpted the famous figures of celebrity mothers Halle Berry, Alicia Keys, and Hilary Duff — at a private West Hollywood gym on July 2, 2012.
The Fashion Star mentor, 31 — who reportedly tipped the scale at 210 lbs. at the height of her pregnancy — has been power-walking and hitting the gym since giving birth to daughter Maxwell Drew on May 1.
And Simpson has plenty of incentive to get back in shape.
Apart from hoping to slim down to her daisy-duke physique, the new Weight Watchers spokeswoman has a bit of extra motivation: She will reportedly rake in $4 million for reaching 130 pounds by the year’s end.
The singer and fashion mogul was first spotted hitting the Pasternak in early June. After Maxwell’s birth (the baby girl weighed 9 lbs 13 oz), Simpson took time to heal from her C-section — and then it was back to the gym.
