Her Melrose Place gig may be over (she shot her last episode March 24), but Josie Bissett (left) has a much more important role coming up. "I’m going to be a mom," she says. "That’s a pretty big job." In fact, she is more than six months’ pregnant (although you can’t tell by looking at her), and she is glad to have some downtime while her husband, Rob Estes, moves from Melrose to Outreach, a pilot for WB in which he plays a doctor. The newest actor in the family is expected to make his curtain call in July. His name will be Mason.
