Actress Melissa Joan Hart is pregnant with her third baby.

The former Sabrina The Teenage Witch star, who turns 36 on Wednesday, recently told Life & Style magazine she and husband Mark Wilkerson were interested in adopting a child -but it appears they're going the natural route first.

She told the publication, "We definitely want to add to our family. We're interested in adopting as well. We're just starting to explore that."

Hart and Wilkerson wed in 2003, and they had their first child, Mason, in 2006. They welcomed their second son, Braydon, in 2008.
