Melissa Joan Hart

Melissa Joan Hart flaunted her new bikini body on Instagram Tuesday. The actress posted a photo of herself in a coral swimsuit and floppy hat to show off her 40-pound weight loss.

"It's not everyday [sic] I like to show a lot of skin but these days I'm feeling confidant [sic]. Thanks Nutrisystem!" Hart wrote.

The mother of three gained 60 pounds when she was pregnant with her son Tucker in 2012. She teamed up with NutriSystem a few months later and lost 20 pounds by April 2013.

What do you think of her new look?
