Williams regularly posts skin and beauty routines to Instagram and the latest shows her morning routine accompanied her two-year-old daughter.
She captioned the video: “@OlympiaOhanian is still too young for eye masks but she sure can work that beauty blender!”
In the video Williams says: “So normally I do my night routine, I never do my day routine or my morning routine.
“So I wanted to show you my morning routine, and Olympia wants to show you too.”
Throughout the film Williams is explaining her routine while Olympia is playing with her beauty blenders.
Williams had Olympia in 2017 with husband Alexis Ohanian.
