"Happy birthday Reese dawg, you're the best there is," added The Mindy Project star, 42. "So lucky to be continually inspired by my friend. Love you forever. ❤️"

Witherspoon's close friend and Big Little Lies costar Dern, 55, chimed in on the birthday love with a carousel of playful images featuring her pal and wrote, "It's International I Love Reese Witherspoon Day! Happy birthday to my amazing sister."

"With every year, her bright light shines even brighter, and I find even more reasons to love her and a greater appreciation for all that she does," Witherspoon's daughter Ava Phillippe captioned a black-and-white image of her mom. "Happy happy birthday to the brilliant, joyful, fiery, thoughtful, and gorgeous woman that I am lucky enough to call my mom. ❤️"

Tuesday was an extra-special day for Witherspoon, as it also saw the premiere of the trailer for Where the Crawdads Sing, the upcoming film adaptation of Delia Owens' bestselling 2018 novel that is produced by Witherspoon's company Hello Sunshine.

The actress selected Crawdads as her Reese's Book Club pick in September 2018, one month after the book came out. The novel appeared at the top of The New York Times Fiction Best Sellers lists in 2019 and 2020, and also held the honor of being Amazon's top-selling fiction book in 2019.

Witherspoon shared the movie's trailer to her Instagram feed on Tuesday and wrote, "The gift of all gifts! 💫 Thrilled to share the official trailer for @crawdadsmovie, coming to theaters this July."

"This story has such a special place in my heart and to see @authordeliaowens words come to life is true movie magic! 🦐🌿 🌅 🛶 @hellosunshine @sonypictures," she added.
