The 34-year-old took to Instagram on Saturday to show off her toned legs during a holiday photo shoot, reported People magazine.
In two different photos, Simpson posed on her knees, then stood with her arms up in the air showing off a little black dress with fringed sleeves.
Earlier this year, Simpson opened up about her recent weight loss, which she attributed to a Weight Watchers diet plan and sessions with celebrity fitness trainer Harley Pasternak.
