Serena Williams' Daughter, Olympia, Crashes Her Photo Shoot With A 'Princess Dress On'

3-year-old Olympia was all dressed up as she jumped into her mom Serena Williams' photoshoot! The mother-daughter duo twinned in blue. So cute! Serena Williams, 39, was all glammed up for a S by Serena photoshoot — her eponymous clothing brand — when her daughter Olympia, 3, with husband Alexis Ohanian hilariously "jumped in"! The toddler looked just like her tennis star mom as she got ready for her close-up, in a princess dress no less. Olympia channeled Cinderella with a glam up-do to go with her ice blue dress, rocking a sweet pair of gold glitter bow flats on her feet.
