Qai Qai is the doll of Serena Williams 1-year-old daughter, Alexis Olympia.

Shes got her own Instagram and quite the following for an inanimate object.

But never underestimate a dolls magic and a mothers sense of humor.

On Sunday the tennis champ posted a pic of Alexis Olympia and Qai Qai sharing a ride while dad Alexis Ohanian towed them.

Is it just us or does Qai Qai seem to come alive whenever the camera is near?
