Reese's second child, Deacon — whose dad is also Ryan Phillippe — was born on Oct. 23, 2003. Although we love his unique first name, the fact that he shares his middle name with his mom's first (though technically, it's her middle name, too, as her full given name is Laura Jeanne Reese Witherspoon) is too cute!
On his fifteenth birthday, Reese shared the above photo on Instagram and gushed about her middle child: "Happy Birthday to my wonderful, creative, kind, talented boy @deaconphillippe! Everyday you teach me something new about beats, Fort Nite dances, fantasy football and cool sneakers. What a gift to be your mom. I love you, buddy! (P.S. When did you get so tall!?)"
