Matt Damon and wife Luciana welcomed baby girl Gia Zavala yesterday (Wednesday, August 20). “Everyone’s doing great,” Damon’s rep revealed to People magazine. “She is a healthy baby girl.” Baby Gia Zavala is the newest addition to the quickly expanding Damon family and is little sister to Isabella, 2, and Alexia, 10. Damon is a “phenomenal” father, his pal George Clooney told People magazine recently. “He absolutely adores those kids. He’s doing it really well.” The reigning “Sexiest Man Alive” is planning on taking a break from acting to get in some much needed downtime with his family. “[I’m] taking the rest of the year off,” Damon told USA Today. “I’m just hanging out with my family.”
