Lindsay Lohan isn’t just any mom—she’s a cool mom.

The Mean Girls alum celebrated her son Luai‘s third birthday on July 17 with a family photo featuring her husband Bader Shammas.

In the heartwarming snapshot, Luai—whose face Lohan, 40, chooses not to show on social media—gave his dad a sweet kiss on the cheek while his mom held him in her arms. The trio all coordinated in white, with Lohan in a waffle-knit sweater, Luai wearing a Toy Story pullover, and Shammas sporting a hoodie from Gurney’s Montauk Resort.

“Happy 3rd Birthday to the greatest gift of our lives, our beautiful Luai,” Lohan captioned the picture in her July 17 Instagram post. “You made our world brighter the moment you arrived, and every day since has been filled with more love, laughter, purpose, and gratitude than we ever imagined possible.”

“Watching you grow into the kind, curious, joyful little boy you are has been the greatest privilege of our lives,” she continued. “We hope you always stay true to your beautiful heart, dream big, be brave, be kind, and never lose your sense of wonder.”
