Serena Williams and husband Alexis Ohanian clearly dote on daughter Olympia.

And the proud parents showed their devotion to their two-year-old in a new photo shared by 39-time Grand Slam tennis champ Serena at the wedding of Alexis’ sister Hayley.

‘She took her flower girl job very seriously!!! @hexner14 @js_poodles congrats. So happy for you both,’ Williams captioned a series of photos on Instagram.

The images showed Serena in a pink Azazie Kaleigh bridesmaid gown and her daughter in a white flower girl dress.

William’s husband, Alexis Ohanian, 36, can also be seen in one of the photos as the two lift little Alexis into the air, each holding one of her hands.
