Hayden Christensen might have played one of the most infamous fathers in movie history, but he's also a real-life dad to a tween of his own - who looks just like her mom! On Friday, August 15, Christensen, 44, stepped out at a Chicago Cubs game with Briar Rose Christensen, his daughter with ex Rachel Bilson. The duo were on hand to sing "Take Me Out to the Ballgame" during the game's 7th-inning stretch.
