Reese Witherspoon and Ryan Phillippe may no longer be together, but they came together on social media this weekend to wish their daughter Ava a happy 18th birthday. "Happy 18th birthday to my sweet girl," Reese wrote alongside a throwback photo of her and a toddler-aged Ava. "Your kindness, grace, intelligence, and humor never cease to amaze me. I love you and your huge heart and I feel so lucky that I get to be your mom."
Meanwhile, Phillippe shared several pics of Ava at all ages, writing, "Happy birthday, punk. I love you more than any strangers need read...Even though you're no longer a child, you'll always be my little girl. Happy 18th, princess." Aww!
