Jessica Simpson is allegedly eager to lose more weight.
The Weight Watchers spokesperson, who lost 50 pounds before marrying Eric Johnson in Montecito, California earlier this month, is said to be determined to stick to her strict diet and exercise regime.
A source close to the 33-year-old beauty, who has a son, Ace, 13 months, and daughter Maxwell, two, with her husband, told In Touch Weekly magazine: "She's been the smallest she's been in years, and she still doesn't think it's good enough.
"She is determined to get even thinner."
A second insider claimed: "[Jessica] wants to get down to 93 pounds. She's become an exercise addict.
"She walks six miles a day, strength-trains three times a week and constantly runs on a treadmill. She's gotten so carried away, she's fainted on a few occasions."
The blonde beauty recently admitted she doesn't want any more children despite having a "beautiful life" with her family.
She also opened up about her new husband and gushed: "I've waited a long time to find someone as wonderful as he is, and I look forward to raising our children together and growing together. With Eric, it's only just begun."
