#29: Melissa Joan Hart
Melissa Joan Hart made young audiences jealous with her supernatural powers on the TGIF hit sitcom Sabrina, The Teenage Witch. But long before she did that, she was making younger teens jealous of her super cool style in Clarissa Explains it All on Nickelodeon. So, Melissa is an important veteran of teen comedy shows.

Perhaps that’s why it’s so difficult for us to think of her as a grown woman with three children. But that’s precisely what she is today. She married musician Mark Wilkerson in 2003, and they welcomed their first son in 2006. They now have two other sons and live in Nashville.
