The actress and her boyfriend of seven years, Star Wars actor Hayden Christensen, are expecting their first child together, People reports. There's no news yet on whether it's a boy or girl or when the baby is due, but there's little doubt that Bilson is thrilled. 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." Congratulations to the happy couple! Plus, see Bilson's best looks ever in our gallery.
