Hudson captioned the sweet video with an emoji-filled message for her fans. "Thank you everyone for the overwhelming love and birthday wishes!" she wrote. "My heart is crazy happy. And the most precious gift today is the steady, ever growing, non wavering love for my children and from my children. Thank you boys for making today so beautiful."
One of the people sending Hudson birthday love was pal Reese Witherspoon, who shared a sweet shout out of her own on Instagram.
"Happy Birthday @katehudson!!" wrote Witherspoon. "Keeping [sic] shining bright with your gorgeous spirit!"
The Deepwater Horizon actress had another birthday to celebrate over the weekend, however: that of her friend Jennifer Meyer, whose star-studded invite list included Katy Perry and her ex, Orlando Bloom, as well as Jennifer Anniston and Justin Theroux.
