“Happy Birthday to my glorious girl @avaphillippe!” Witherspoon wrote in her caption, along with emojis of hearts, a cake and a partying face. “It's the joy of my life to watch you grow and become the most inspiring, thoughtful, creative, dynamic, funny woman. I have learned so much from being your mom. How lucky is that??!! I love you to the stars and back!”
Fellow celebs flooded the comments with birthday wishes to the young model and artist, including Chelsea Handler, Gwyneth Paltrow, Viola Davis, Julianne Moore, Kerry Washington and more.
In Witherspoon's slideshow, we couldn't get over how much she and Ava looked like twins, with both even rocking the same wavy hairstyle. However, the two looked a little more different in the second slide, which was a major throwback of the Election star holding her daughter when she was a small girl.
