This is the first child for the couple, who have been together for seven years. The pair announced that they were expecting in May, and there was little doubt the new mom was thrilled at the news. The O.C. star has expressed her desire to have a family for a long time, and told InStyle back in 2005 that becoming a mother was on her bucket list. “Having kids and a family is the most important thing,” she said. “I’ve always wanted to be a mom.” And true to her always-stylish form, Bilson kept us on her toes throughout her pregnancy with one fashionable maternity look after another. Congrats to the expanding family!
