Reese Witherspoon’s 19-year-old daughter, Ava Phillippe, penned a touching tribute to her mom on Instagram on Wednesday.

"This is the gorgeous woman who taught me about the power of graciousness, love, ambition, and hard work," she began alongside a seemingly candid photo of Witherspoon. "She inspires me every day to live with gratitude for the life I’ve been given and compassion for others. I’m thinking about her a little extra today, that’s all."
