Melissa Joan Hart has dropped 40 pounds, and she is ready for her big reveal...almost! The mother of three shared a sexy snapshot from the set of her latest Nutrisystem commercial which is set to debut this spring. During the shoot the 37-year-old actress opened up about her weight loss telling Entertainment Tonight, "For me, it was important to bond with my child, as opposed to 'lose the weight.' So I waited until I was ready, and I knew I had the time, and then I made it ia priority that I would eat well." Melissa gained 60 pounds while pregnant with her now 1 1/2 year old son, Tucker.
