Due in April 2013, the baby-to-be is the first for Mitchell and accountant husband Michael Cameron. After dating for five years, she and Cameron, 32, got engaged in 2006 and tied the knot in October 2008 in Ravello, Italy; among the bridesmaids was her former costar Jessica Biel, who loved the wedding locale so much that she married Justin Timberlakein the same region four years later.
"Can't wait to share this journey with you. We are so thrilled to become parents," Mitchell wrote when she announced her pregnancy earlier this month. "It couldn't be a more exciting time! Thank you for all the well wishes!"
