Lookin' good, Jessica Simpson!

The new mom to Maxwell — who gave birth to her daughter with fiance Eric Johnson in May — stunned in Tampa, Florida Saturday, Nov. 17, showing off her incredible post-baby weight loss as she posed for photos at an event for her Jessica Simpson Collection.

Simpson, 32, opted for a funky bright pink blazer and bootcut jeans for her afternoon out. (Sister Ashlee was also on hand to show her support for the Fashion Star mentor.)

Last month, Simpson told Us Weekly she had lost all but 10 of the 70 pounds she gained while pregnant. "I feel positive about how I've done so far and really good about the goals I have set," the Weight Watchers spokeswoman said. "Most people can tell a difference every time they see me, which lets me know I'm making progress."

Her trainer Harley Pasternak told Us he's blown away by his client's determination.

"In over 20 years, I've never seen as consistent a weight loss," the fitness guru shared. "Jessica's right where she needs to be . . . She's gotten so much stronger."
