They're famous, they played roommates together on a hit syndicated TV series and now these former child stars are both pregnant -- for the second time! Can you guess who they are? Our own THEA ANDREWS visited the Us Weekly magazine shoot where these Hollywood BFFs dished on their differing pregnancies (one has morning sickness, one doesn't!) and being due almost "a day apart." Need another hint? Both are 31 years old, but one's a blonde and the other's a brunette. Watch the video to see who they are and pick up Us on Friday!
