Ava, who was born on Sept. 9, 1999, is Witherspoon's oldest child and her first with ex-husband Ryan Phillippe. While Ava has always resembled her mama, she and Witherspoon look scarily alike now that she's a young adult.
On Witherspoon's birthday in 2019, Ava gushed about her mom, writing on Instagram: "This is the gorgeous woman who taught me about the power of graciousness, love, ambition, and hard work. She inspires me everyday to live with gratitude for the life I've been given and compassion for others." Witherspoon followed up with, "How did I get so lucky to have a daughter like you?"
Aw! Witherspoon also got sentimental when she spoke to Ellen DeGeneres about sending Ava off to college. "It's weird when your children go away to college. It's hard. I never imagined how it felt for my mom." She added, "I might have gone into her empty room, laid down on her bed, and cried."
