Rachael Leigh Cook and actor/director husband Daniel Gillies are the proud parents of a second child, Theodore Vigo Sullivan Gillies, born on April 4—just 18 months after older sister Charlotte Easton. "Welcome to the party, Little Buddy," Cook, 35, tweeted. "We love you so much." The news of the pregnancy came as a shock to Cook, star of Perception, and The Originals star Gillies, 39, who joked in a statement in January: "We're as happy as we were surprised by this wonderful news! We haven't slept since 2013 and welcome advice from all parents who survived Two Under Two."
