Jessica Simpson officially unveiled her post-baby body on the premiere of Katie Couric's new talk show Monday.
Simpson says she's lost more than 40 pounds since giving birth to Maxwell Drew Johnson in May.
The star, who's only five feet, four inches tall, says she weighed 170 pounds at one point during her pregnancy and has struggled to shed the weight.
Earlier this year, Simpson signed a $3 million deal to be the new face of Weight Watchers and says she's about 10 pounds away from her goal weight.
Simpson also appeared as a guest host Tuesday morning on Good Morning America.
