Melissa Joan Hart has lost 40 pounds with the help of Nutrisystem since giving birth to her third child, son Tucker in September of 2012, and only ET is with the "Melissa & Joey" star as she shows off the results in a sexy blue one-piece!
ET was on the set of her latest commercial as the spokesperson for Nutrisystem, where Melissa felt "pretty amazing" in her bathing suit.
"I felt prepared. I was confident," she smiles. "I don't wear bikinis even when I go to the beach, so when I put it on in front of the cameras and all these people, and my husband showed up -- it's nerve-wracking but the feeling is very satisfying."
Melissa, who gained 60 pounds during her third pregnancy, says she didn't feel as much pressure to lose the baby weight so quickly this time around as opposed to her first pregnancy.
"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 a priority that I would eat well," she says. " ... In the beginning, I felt an uncomfortable pressure that I rebelled against, but this third time, I had to go back on camera, I wanted to look great, so I focused on it once I knew I had the time in my schedule."
And is she happy with her current body?
"I am actually -- I am really happy where I am," the 37-year-old actress says. "I could live like this. I'm on a good path -- I love where I'm at and I feel amazing."
Check out the video to hear if Melissa and her husband Mark are planning to have more kids, and how she actually protects her kids from paparazzi by putting them in front of the cameras.
