Charlize Theron, 45, celebrated Daughter’s Day with the cutest post on Instagram! For the special day on Sept. 25, the Atomic Blonde star shared a slideshow filled with adorable photos of her daughters Jackson, 8, and August, 3. Charlize cuddled with her girls in front of a birthday cake in the front slide, and the rest of the post revealed just as cute memories: the girls smiling on a boat, sipping from cereal bowls, and sharing a sweet kiss!
