The blond and always bubbly mother-daughter duo ditched their heels and clutches for tennis balls and rackets, bringing their best game to center court for a match of tennis.
They were so intent on playing the game that they didn't even let their draping ball gowns get in the way of their match alongside Wimbledon runner-up, Djokovic, who played host for the night.
All the fun and games were for a good cause, as the event raised more than $1.5 million for Novak's charity, which supports disadvantaged children in Serbia.
So, even though Djokovic may not have won Wimbledon, he was definitely the winner of the night.
