See Jessica & Eric take take baby Maxwell on first flight
Jessica Simpson has been open about her weight struggles since giving birth to baby Maxwell six months ago, but now she’s on the right track to trimming down, as she shows off her sleeker figure in her second Weight Watcher’s commercial — and Celebuzz has the photo to prove it.

The new mommy’s first Weight Watchers commercial aired in September, but only featured the pop star from the waist-up — giving her fans something to look forward to when she finally makes the big reveal. This time around, the Fashion Star judge looks toned and ready for her head-to-toe close-up.

The 32-year-old let her signature blonde locks flow in a monochrome black ensemble to flatter her slimmer shape — and tweeted about the experience:

The petite, Texas-born songstress — who’s engaged to former NFL pro Eric Johnson — reportedly gained 70 pounds during her pregnancy, but has finally lost over 60 pounds of her baby weight.

Simpson said she’s been able to shed the pounds by maintaining a healthy diet and rigorous exercise routine. She told Us Weekly she’s been stepping to a slimmer her, doing “at least 14,000 steps a day,” along with regular fitness sessions with celebrity trainer Harley Pasternak.

The blonde bombshell also appeared on Katie Couric’s talk show Katie, where she described her weight-loss plan: “I set small goals for myself so that I could achieve them every week. That’s been great. I have lost weight every week, thank God. But I have worked really, really hard,” Simpson said.

“I have to shoot a new season of my show Fashion Star. So, I want to be in all of the pretty dresses and the designer gowns. I am 10 pounds away from that. By the time I am shooting, I will be smaller.”
