Melissa Joan Hart is finally sharing the secret to her slim post-baby bod!
The 36-year-old mother of three has been announced as the new Nutrisystem spokeswoman, and the former Sabrina, the Teenage Witch star reveals she's already lost 20 pounds on the diet plan since giving birth to her third child in September.
"I love working with Nutrisystem," the actress—who currently stars on the hit ABC comedy Melissa & Joey—said in a statement to ET Online. "The program is really delivering results for me and I look forward to long-term success, staying motivated and helping others do the same."
