Although her character on Weeds may have trouble adopting — the drug-dealing thing could be a problem! — Mary-Louise Parker didn't have to worry about that when she decided to add to her family. The single mom, who has a 3-year-old son with actor Billy Crudup, adopted a baby girl from Africa. The ladies were first spotted together while traveling from New York to Los Angeles for the Emmy Awards in September 2007. "Mary-Louise is such an incredible mom," a source told People when confirming the story. "She couldn't be happier about this." We're pretty fired up over it, too.
